New Cage Phosphonates Containing Halomethyl Group: Synthesis and Some Properties

Abstract

A method was developed for the synthesis of new unsymmetrical cage phosphonates containing terminal halo(bromo, chloro)methyl groups as a result of the reaction of (2-ethoxyvinyl)phosphonic dichloride with halogen-N-(3-hydroxyphenyl)acetamides in trifluoroacetic acid. New cage phosphonates containing one or two phosphonium groups were obtained as a result of the reaction of triphenylphosphine with the corresponding cage phosphonates. It was shown that the type of products formed in this reaction depends on the nature of the halogen atom in the halomethyl group of the cage phosphonate.
