Synthesis of Dialkyl l-Methyl-2,2-dichlorocyclopropylcarbonyl-phosphonates and Alkyl (l-Methyl-2,2-dichlorocyclopropylcarbonyl)arylphosphinates

摘要

One of the promising directions in synthesis of phosphorylated small carbocycles is the reaction of three-coordinate phosphorus derivatives with functional derivatives of cyclopropane and cyclobutane [1,2].Among such derivatives,halocyclopropanes are the most widely used,whereas representatives of other classes were used only in a few works.In this connection,continuing our previous studies [3,4] and aiming to broaden the synthetic potential of cyclo-propanecarboxylic acid derivatives,we have studied the reaction of l-methyl-2,2-dichlorocyclopropylcarbonyl chloride I with esters of phosphorus(III) acids.
