PREPARATION AND REACTIONS OF trans- (R = Me, Ph or C6H4Me-p)
McPherson, Helen,Wardell, James L.
, p. 261 - 266 (1983)
Formation of trans- (R=Me, Ph or C6H4Me-p) has been achieved by the oxidative addition of ClCH2SR to (PPh3)4Pt in refluxing PhH.The reaction of ClCH2SMe with (PMe2Ph)4Pt led to cis-.The reaction of trans-(PPh3)2Pt(CH2S
