Cycloaddition and chlorotropic transformations in reactions of dichloromethylenetrifluoroacetamide with phosphites
摘要:
Reactions of dichlormethylenetrifluoroacetamide with triphenyl phosphite, diethylchlorophosphite (o-phenylene)diethylamidophosphite, (o-phenylene)chlorphosphite, and 2-fluoro-3-isopropyl-5-tert-butyl-1,3,2-oxazaphospholine proceeded as cheletropic [4+1]-cycloaddition. The formed lambda(5)-1,4,2-oxazaphospholines underwent 1,3-migration of the chlorine atom in C=N-C cyclic triad.
