New hydrogenation and isomerization reactions involving thiaplatinacycles derived from benzothiophene

Iretskii, Alexei,Adams, Harry,Garcia, Juventino J.,Picazo, Graciela,Maitlis, Peter M.

, p. 61 - 62 (1998)

Hydrogenation of the thiaplatinacycle [Pt{C,S-(CH=CHC6H4S)}(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.
