Multivalent metal salts, such as ferric chloride and sulfate, are active and versatile catalysts for the amidation of aliphatic fatty acids with long-chain aliphatic amines.
多价金属盐,如氯化铁和硫酸盐,是用于脂肪族脂肪酸与长链脂肪胺酰胺化的活性和通用催化剂。
Substrate-Selective Dehydrocondensation at the Interface of Micelles and Emulsions of Common Surfactants
Scratch the surface: Dehydrocondensations between carboxylates and amines by using an amphiphilic 1,3,5‐triazinylammonium‐based coupling agent were accelerated by the interfacial effect of micelles and emulsions of commonsurfactants (see figure). The reaction of carboxylates was promoted by both anionic and nonionic surfactants, and that of amines was promoted by only a nonionic surfactant. High selectivities
