A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 13406-29-6, Name is Tris(4-(trifluoromethyl)phenyl)phosphine, molecular formula is C21H12F9P. In a Article，once mentioned of 13406-29-6, name: Tris(4-(trifluoromethyl)phenyl)phosphine
The alpha-amidoalkylating properties of 1-(N-acylamino)alkyltriarylphosphonium salts with weakened Calpha-P+ bond strength are discussed and examined. It is demonstrated that such type of phosphonium salts reacts smoothly with a diverse array of carbon- and heteroatom-based nucleophiles, including 1-morpholinocyclohexene, 1,3-dicarbonyl compounds, benzotriazole sodium salt, p-toluenesulfinate sodium salt, benzylamine, triarylphosphines, and other P-nucleophiles. Reactions are conducted at room temperature, in a short time (5?15 min) and mostly without catalysts. Simple work-up procedures result in good or very good yields of products. The structures of known compounds were established by spectroscopic methods and all new compounds have been fully characterized using 1H-, 13C-, 31P-NMR, IR spectroscopy, and high-resolution mass spectrometry. Mechanistic aspects of described transformations are also performed and discussed. It was demonstrated that unique properties make 1-(N-acylamino)alkyl-triarylphosphonium salts with weakened Calpha-P+ bond strength interesting building blocks with great potential, especially in alpha-amidoalkylation reactions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: Tris(4-(trifluoromethyl)phenyl)phosphine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13406-29-6, in my other articles.
