Abstract
The reaction of 3-phenyl-2-phenylethynyl-1,3,2λ3-oxazaphospholidine with nitrilimines is a multistep process involving formation of the diazaphosphorine ring and cleavage of the oxazaphospholidine ring. The final products are the substituted 4-[N-phenyl-N-(2-chloroethyl)amino]-1,4-dihydro-1,2,4λ5-diazaphosphorines. According to X-ray structural data obtained for 4-[N-phenyl-N-(2-chloroethyl)amino]-1,4-dihydro- 1,5-diphenyl-3-ethoxycarbonyl-1,2,4λ5-diazaphosphorine, the heteroring of these compounds has the conformation of a flattened P-envelope.
