Abstract: | N-(Trichloroacetyl)trichloroacetylimidoyl chloride reacts with trialkyl phosphites with substitution of the imidoyl chlorine atom and formation of C-phosphorylated heterodienes. The reaction with triphenyl phosphite or o-phenylene diethylphosphoroamidite proceeds as 4+1]-cycloaddition to give mono- or spirocyclic oxazaphospholines with the five-coordinate phosphorus atom. Dialkyl or diphenyl hydrogen phosphites add across the C = N bond of imidoyl chloride to give labile N-( -phosphorylated) trichloroacetamides. |
