SOME PROPERTIES OF 1-PHOSPHORUS(IV)-SUBSTITUTED CYCLOALKANECARBOXYLICACIDS AND THEIR DERIVATIVES

An x-ray structural study of single crystals of 1-diphenylphosphinyl-c yclo-propane- and 1-diphenylphosphinylcyclobutanecarboxylic acids was conducted. 1-Phosphorylated cycloalkanecarboxylic acid amides were obt ained from the corresponding acids by the reaction with thionyl chlori de 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 o f the cyclic structure and yields phosphoric acid silyl esters, and th e corresponding cycloalkylphosphonic and cycloalkylphosphinic acids we re synthesized by their hydrolysis in soft conditions.
