Application In Synthesis of Methyl 3-phenyl-2-propenoate. The Name is Methyl 3-phenyl-2-propenoate. Through research, I have a further understanding and discovery of 103-26-4.

The aim of this research was to determine the chemical constituents and toxicity of the oil derived from Alpinia katsumadai seeds against Tribolium castaneum, Liposcelis bostrychophila and Lasioderma serricorne. The essential oil was obtained by hydrodistillation and was investigated by gas chromatograhy/mass spectrometry (GC/MS). The principal components of the essential oil were methyl cinnamate (64.2 %), cis-4-decen-1-ol (7.3 %) and octahydro-cis-2H-Inden-2-one (6.7 %). The essential oil and the two individial compounds exhibited potential insecticidal activities against three stored product insects. The essential oil possessed contact toxicity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 52.6 mu g/adult, 17.4 mu g/adult and 35.6 mu g/cm(2), respectively). Methyl cinnamate was the main contributor to its contact activity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 5.0 mu g/adult, 2.2 mu g/adult and 23.5 mu g/cm, respectively). The contact toxicity and repellent activity of the essential oil and cis-4-decen-1-ol against T. castaneum, L. bostrychophila and L. serricorne were recorded for the first time in this paper. A. katsumadai oil exhibited strong repellent activity against T. castaneum and L. bostrychophila, even at low concentrations. The results provide a basis of the development and utilization as biopesticide for control of insects.

Conventional methods to improve the flame retardancy of polymeric materials usually involve the use of flame-retardant elements such as Cl, Br and P, however, their use may bring more smoke and toxic gases hazards, and more importantly, cause non-negligible environmental and ecological problems. In this work, we put forward a novel green strategy that eliminates the use of any conventional flame-retardant elements to improve the flame retardancy by incorporating a synergistically cross-linkable structure (named PN) containing phenylacetylene and phenylimide groups. The resulting PN copolymer exhibited an excellent 55% lower smoke release rate and 68% lower heat release rate than the pure polymer, as well as a high LOI value of 32% and UL-94 V-0 rating with excellent anti-dripping performance. TG-DSC, rheological and FTIR results proved the high cross-linking ability of the PN copolymer due to the synergistic cross-linking effect between the imide-isoimide rearrangement of phenylimide and the self-cross-linking of phenylacetylene. The SEM, Raman and Py-GC/MS results further upheld the condensed phase flame-retardant mechanism. This eco-friendly synergistic cross-linking strategy provided new perspective for the design and synthesis of polymeric materials with excellent flame retardancy, great anti-dripping performance, and low release of heat, smoke, and toxic gas.

p-Coumaric acid is a known inhibitor of tyrosinase, an enzyme involved in the initial steps of the melanin synthesis in human and other species. However, its low lipophilicity impairs its penetration through skin and efficacy as antimelanogenic agent indeed. Accordingly, this paper reports the assessment of several coumaric acid derivatives as tyrosinase inhibitors and antimelanogenic agents in in vitro, in silico and ex vivo assays. The compounds were designed with modifications in the aromatic and acid moieties of p-coumaric acid, being the coumarate esters the most promising derivatives. The compounds showed higher tyrosinase inhibitory activity (pIC(50), 3.7-4.2) than the parent acid, being compounds 1d, 1e and 1f the most potent inhibitors. Docking analysis showed that these esters are competitive inhibitors per se, and act independently of a redox mechanism as suggested by DPPH assays. Moreover, the esters showed efficacy in reducing the melanin deposition in human skin fragments at 0.1% concentration, especially compound le. In summary, there is an important equilibria between tyrosinase affinity and lipophilicity that must be considered to get effective antimelanogenic agents with adequate permeability in the skin.

Polyaniline coated on particles of celite is used as support to load palladium catalyst. This heterogenized Celite center dot PANI center dot Pd system, is used as an efficient catalyst for chemoselective hydrogenation reactions. The catalyst is characterized by usual spectral, analytical techniques and studied for hydrogenation reactions at ambient conditions. The mild reaction conditions allow the control over the reactions and excellent selectivity is achieved in number of conversions. Hydrogenation of a carbon-carbon double bond was favored over other polar pi-bond systems, while labile functional groups such as benzyl ether, benzyl esters, cyano, nitro and halogen remained unaffected. Primary amines were converted to N,N-dimethyl amines with formaldehyde, the double bond of coumarin was selectively hydrogenated without opening of the lactone functionality.

N-Acylpyrrole-type amides are a class of versatile building blocks in asymmetric synthesis. We report that by employing Ni(COD)(2)/2,2 ‘-bipyridine (5 mol%) catalytic system, the direct, catalytic alcoholysis of N-acylpyrrole-type aromatic and aliphatic amides with both primary and secondary alcohols can be achieved efficiently under very mild conditions (rt, 1 h) even at gram scale. By increasing the catalyst loading to 10 mol%, prolonging reaction time (18 h), and/or elevating reaction temperature to 50 degrees C/80 degrees C, the reaction could be extended to both complex and hindered N-acylpyrroles as well as to N-acylpyrazoles, Nacylindoles, and to other (functionalized) primary and secondary alcohols. In all cases, only 1.5 equiv. of alcohol were used. The value of the method has been demonstrated by the racemization-free, catalytic alcoholysis of chiral amides yielded from other asymmetric methodologies.

A palladium organic-inorganic hybrid magnetic nanocatalyst for the Heck-cross coupling reactions was developed. This newly synthesized phosphine-free PdMNPs catalyzed Heck-cross coupling reactions in short reaction times (20-30 min) and high to excellent yields (75-93%). The catalyst was separated simply by an external magnet and reused in 10 successive runs without significant decrease in catalytic activity. The structure of the catalyst was established by Fourier transform infrared, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometer and thermogravimetric analysis analyses.

We report herein a visible-light-promoted, highly practical carboxylation of readily accessible aryl triflates at ambient temperature and a balloon pressure of CO2 by the combined use of palladium and photoredox Ir(III) catalysts. Strikingly, the stoichiometric metallic reductant is replaced by a nonmetallic amine reductant providing an environmentally benign carboxylation process. In addition, one-pot synthesis of a carboxylic acid directly from phenol and modification of estrone and concise synthesis of pharmaceutical drugs adapalene and bexarotene have been accomplished via late-stage carboxylation reaction. Furthermore, a parallel decarboxylation-carboxylation reaction has been demonstrated in an H-type closed vessel that is an interesting concept for the strategic sector. Spectroscopic and spectroelectrochemical studies indicated electron transfer from the Ir(III)/DIPEA combination to generate aryl carboxylate and Pd(0) for catalytic turnover.
