Abstract

The reaction of phosphines and amides with diethyl azodicarboxylate (DAD) produced phospha-h5-azenes. Thus aromatic amides and those aliphatic amides with electron- withdrawing substituents gave N-acyl-P, P, P-triphenylphospha-h5-azenes (5) when triphenylphosphine (TPP) was employed. Both aryl-and alkylsulfonamides reacted with TPP and DAD to produce the N-sulfonylphospha-X5-azenes (9). Diphenylphosphinamide (10) ...
