Chiral (S,S)-(Phebox)PtCl complex 2 [Phebox = bis(oxazolyl)phenyl] and its cationic complexes (Phebox)Pt(OTf) (3) and [(Phebox)Pt(H2O)](BF4) (4) were synthesized by the transmetalation reaction of (Phebox)SnMe3 (1) with K[PtCl3(C2H4)](H2O) and subsequent treatment with silver salts. Both cationic co...
