The catalytic performances of 1–7 for dehydration of amides to nitriles were explored by comparing three factors: (1) different chalcogen coordination atoms Y; (2) R' group of the phosphine moiety; (3) R substituent group at the phenyl ring. It is confirmed that 5 with S as coordination...
The mechanism is thought to involve initial [3,3] sigmatotropic shift of the allyl group, followed by cleavage of the N–N bond to give a thiaza-allyl radical, which then undergoes cyclization, rearrangement, and alkyl group extrusion <2001J(P1)424>. (54) The reaction of dimedone with ...
