✦ Synopsis

The complexes PPh,[X(t-C-C-Ph),] with X = C1 ( l ) , Br (2), I (3), PPh4[ Br(Br-C-C -Ph),] (4), and NMe,[F(I-C-C -Ph),] (5) were prepared from the corresponding salts PPh4X and NMe4F, respectively, with the 1-halogen-2-phenylacetylenes X-C-C-Ph (X = Br, I) in dichloromethane solutions. 1-5 form colourless crystals, which were characterized by vibra--1R (Nujol, em-'): 3 = 613 (vCPBr). -I3C-NMR (DCC13, TMS): 6 = 49.7 (Br-C=C), 80.0 (Br-C==C). -
