The interaction of N-fluoroacetyltrichloroacetamide (1) with PCl5 leads to the formation of N-trichloroacetylfluoroacetimidoyl chloride (3), which is irreversibly isomerized to N-chloro(fluoro)vinyltrichloroacetamide (Z/E≈3:1) in the presence of the catalyst DBU. In the reaction of 3 with phosphites or phosphines, the substitution of chlorine atom by the phosphorus-containing groups is accompanied
