addition, we note a correlation between 1H and 13C NMR chemicalshifts of the acrylamide with GSH reaction rates, suggesting that NMR chemicalshifts may be a convenient surrogate measure of relative acrylamide reactivity. Density functional theory calculations reveal a correlation between computed activation parameters and experimentally determined reaction rates, validating the use of such methodology
1,3-Butadiene plays a key role in modern synthetic chemistry and biochemistry because it is a key intermediate in the synthesis of many drugs. A new and effective method for the synthesis of 4-trifluoromethylated 1,3-butadiene through the fluorinated Heckreaction catalyzed by Pd(0) is described. Without additives, 1-chloro-3,3,3-trifluoropropene (an inexpensive CF3 structural unit that is harmless

The CuI-mediated click reaction of aromatic azides, containing the carboxyl moiety in the ortho position to the azido group, with ethyl prop-2-ynyl methylphosphonate proceeded via a concurrent pathway whereby the formation of acrylamides predominated over "classical" cycloaddition products 1,2,3-triazoles. The reaction appears to be specific toward the ortho-carboxyl-substituted aromatic azides, while
CuI介导的芳香叠氮化物(在叠氮基基团邻位含有羧基部分)与丙-2-炔基甲基膦酸乙酯的并发点击反应是通过并发途径进行的,由此形成的丙烯酰胺比“经典的”环加成产物更重要, 2,3-三唑。该反应似乎对邻羧基取代的芳族叠氮化物具有特异性,而具有其他取代基的芳基叠氮化物不会产生“还原”产物,但会形成预期的点击产物:(1-芳基-1 H -1,2, 3-三唑-4-基)甲基乙基甲基膦酸酯。讨论了反应机理。
