Features of the Reaction of (1,2-Dibromoethyl)(diphenyl)phosphine Oxide with CH- and NH-Nucleophiles
摘要
Abstract
The reaction of (1,2-dibromoethyl)(diphenyl)phosphine oxide with CH-acids (acetylacetone, acetoacetic ester, and malonic ester) in the presence of sodium hydroxide has afforded diphenylphosphoryl-substituted cyclopropanes in high yield. It has been shown that the reaction of (1,2-dibromoethyl)(diphenyl)phosphine oxide with primary arylamines leads to the formation of bis(phosphine oxides), in contrast to alkylamines which lead to phosphoryl-substituted aziridines.
