New hydrogenation and isomerization reactions involving thiaplatinacycles derived from benzothiophene

Abstract

Hydrogenation of the thiaplatinacycle [Pt{C,S-(CHCHC₆H₄S)}(dppe)] 2 (dppe = Ph₂PCH₂CH₂PPh₂) derived from benzothiophene, leads to [Pt{C,S-(CHMeC₆H₄S)}(dppe)] 3 in which 2H have added and a H-shift has occurred; the X-ray structures of 2 and 3 are reported.
