[Pd(PPh3)4] (2) reacts with IC≡CPh and ClC≡CPh in the sense of an oxidative addition to give trans[Pd(C≡CPh)X(PPh3)2] (X = I: 3 a, X = Cl: 3 b). As side products trans-[PdX2(PPh3)2] (X = I: 4 a, X = Cl: 4 b; a and 3 b were characterized by NMR (1H, 13C, 31P) and IR spectroscopies as well as by X-ray single-crystal structure analyses. In the crystals of 3 a and 3 b isolated molecules were found. The Pd-C≡C-Ph unit is linear in 3 a and approximately linear in 3 b [Pd-C≡C 174.2(6)°, C≡C-C 179,0(7)°].
