Not the azadiphosphiridine 2, but the diazaphosphetidine 3 is formed upon reduction of 1 . The intermediate 2 detectable in the reduction is converted by Lewis or Brønsted acids into 3 . With F 3 CSO 3 H as acid, the intermediates of the isomerization, 4 and 5 , could be isolated (R t Bu; XF 3 CSO 3 ).
