New 1,4-naphthoquinone derived by triphenylphosphaneylidene (Ph3P) and N-substituted-hydrazine-1-carbothioamides were obtained during a one-pot reaction of 2,3-dichloro-1,4-naphthoquinone with thiosemicarbazides, Ph3P and in the presence of tri-Et amine (Et3N) as a catalyst. The structure of the ligands was established by ESI, IR, and NMR spectra, in addition to elemental analyses and X-ray structure anal. On subjecting the newly prepared ligands with CuCl2 and Ph3P, autoxidation occurs, and (E)-(2-(1,4-dioxo-3-(tri-Ph phosphanylidene)-3,4-dihydronaphthalen-2(1H)-ylidene)carbamothioyl)hydrazinyl-((triphenylphosphanyl)oxy)copper derivatives were formed in very good yields. The structure of the obtained complexes was proved by ESI, IR, NMR, and UV spectra, in addition to elemental analyses and theor. calculations This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Application of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application of 2253-73-8
