Geffers, Finn J.; Kurth, Florens R.; Jones, Peter G.; Werz, Daniel B. published an article in 2021. The article was titled 《Alkyne Aminopalladation/Heck and Suzuki Cascades: An Approach to Tetrasubstituted Enamines》, and you may find the article in Chemistry – A European Journal.Computed Properties of C5H11NO3 The information in the text is summarized as follows:
Alkyne aminopalladation reactions starting from tosylamides, e.g., (E)-N-(5-(2-(but-2-en-1-yloxy)phenyl)pent-4-yn-1-yl)-4-Me N-((perfluorobenzoyl)oxy)benzenesulfonamide are reported. The emerging vinylic Pd species are converted either in an intramol. Heck reaction with olefinic units or in an intermol. Suzuki reaction by using boronic acids RB(OH)2 (R = C6H5, 4-ClC6H4, 2-thienyl, etc.) exhibiting broad functional group tolerance. Tetra(hetero)substituted tosylated enamines, e.g., I are obtained in a simple one-pot process.N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Computed Properties of C5H11NO3) was used in this study.
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Computed Properties of C5H11NO3
