Reactions of {(C 6 F 5 )Pt[S(CH 2 CH 2 -) 2 ](μ-Cl)} 2  and R 3 P yield the bis(phosphine) species  trans -(C 6 F 5 )(R 3 P) 2 PtCl [R = Et ( Pt'Cl ), Ph, ( p -CF 3 C 6 H 4 ) 3 P; 88-81 %]. Additions of  Pt'Cl  and H(C≡C)  n  H ( n  = 1, 2; HNEt 2 , 20 mol % CuI) give  Pt'C 2 H  (37 %, plus  Pt'I , 16 %) and  Pt'C 4 H  (88 %). Homocoupling of  Pt'C 4 H  under Hay conditions (O 2 , CuCl, TMEDA, acetone) gives  Pt'C 8 Pt'  (85 %), but  Pt'C 2 H  affords only traces of  Pt'C 4 Pt' . However, condensation of  Pt'C 4 H  and  Pt'Cl  (HNEt 2 , 20 mol % CuI) yields  Pt'C 4 Pt'  (97 %). Hay heterocouplings of  Pt'C 4 H  or  trans -( p -tol)(Ph 3 P) 2 Pt(C≡C) 2 H ( Pt*C 4 H ) and excess HC≡CSiEt 3  give  Pt'C 6 SiEt 3   (76 %) or  Pt*C 6 SiEt 3   (89 %). The latter and wet  n -Bu 4 N +  F -  react to yield labile  Pt*C 6 H  (60 %). Hay homocouplings of  Pt*C 4 H  and  Pt*C 6 H  give  Pt*C 8 Pt*  (64 %) and  Pt*C 12 Pt*  (64 %). Reaction of  trans -(C 6 F 5 )( p -tol 3 P) 2 PtCl ( PtCl ) and HC≡CH (HNEt 2 , 20 mol % CuI) yields only traces of  PtC 2 H . However, an analogous reaction with HC≡CSiMe 3  gives  PtC 2 SiMe 3   (75 %), which upon treatment with silica yields  PtC 2 H  (77 %). An analogous coupling of  trans -(C 6 F 5 )(Ph 3 P) 2 PtCl with H(C≡C) 2 H gives  trans -(C 6 F 5 )(Ph 3 P) 2 Pt(C≡C) 2 H (34 %). Advantages and disadvantages of the various  trans -(Ar)(R 3 P) 2 Pt end-groups are analyzed.
