Reaction of the lithium enolate of acetaldehyde, Li(OCHCH2), with cyclothiaphosphazenes
Abstract
Reactions of the lithium enolate of acetaldehyde, Li(OCHCH2), with the mixed ring systems [NS(O)Ph]3–n(NPCl2)n(n= 1 or 2) lead to a complete series of vinyloxy derivatives. The vinyloxy group is stable in subsequent substitution reactions using amines as nucleophiles. The compound [NS(O)Ph]NPCl2[NPCl(OCHCH2)] is a useful precursor in polymerization reactions.
