Some properties of 1-phosphorus(IV)-substituted cycloalkanecarboxylic acids and their derivatives
摘要:
An x-ray structural study of single crystals of 1-diphenylphosphinyl-cyclo-propane- and 1-diphenylphosphinylcyclobutanecarboxylic acids was conducted. 1-Phosphorylated cycloalkanecarboxylic acid amides were obtained from the corresponding acids by the reaction with thionyl chloride with subsequent treatment with primary and secondary amines. It was shown that the reaction of 1-phosphorylated 1-functional substituted cycloalkanes with trimethylbromosilane takes place with preservation of the cyclic structure and yields phosphoric acid silyl esters, and the corresponding cycloalkylphosphonic and cycloalkylphosphinic acids were synthesized by their hydrolysis in soft conditions.
Cycloalkylation of compounds in the series of phosphorus-substituted derivatives of acetic acid
摘要:
1-Phosphoryl-substituted cyclopropanes, cyclobutanes, and cyclopentanes were obtained by the reaction of phosphoryl-substituted esters and nitriles of acetic acid with alpha,omega-dihaloalkanes. The influence of the CH-acidity of the starting compounds and electrophilicity of the alkylating agent on the reaction rate was examined.
