dc.description.abstract | By reacting the dialkynes HC /C(Ar)C /CH [Ar /1,3-C6H4 (mphen), 1,3-(C6HMe3-2,4,6) (mes), 1,4-(C6Me4-2,3,5,6) (dur)] with [AuClL] [L /dimethylsulfide (dms), tetrahydrothiophene (tht)] in the presence of an excess of Et3N the polymeric complexes [AuC / C(Ar)C /CAu]n [Ar /mphen (1), mes (2) dur (3)] were prepared. Upon reaction of these complexes with two equivalents of phosphine or isocyanide ligands (L), complexes [LAuC /C(Ar)C /CAuL] [Ar /mes, L / tBuNC (4), XyNC (5); Ar /dur, L /PPh3 (6), tBuNC (7)] were prepared in good yields. The complex [tBuNCAuC /C(mphen)C /CAuCNtBu] (8) was prepared by reaction of the corresponding diethynylarene with 2 equiv. of [AuCl(CNtBu)] in the presence of NEt3. By reacting the appropriate diethynylarene with 2 equiv. of [Au(acac)PPh3], complexes [Ph3PAuC /C(Ar)C /CAuPPh3] [Ar /mphen (9), mes (10)] were prepared. The carbene complex [(tBuNH)(Et2N)CAuC /C(mes)C /CAuC(NHtBu)(NEt2)] (11) was obtained by reacting the corresponding isocyanide complex 4 with diethylamine. The crystal structures of complexes 9 and 10 have been determined by X-ray diffraction studies. In both cases one of the gold atoms is in an essentially linear environment [CAuP: 176.95(14) (9), 177.19(8)8 (10)] while the other CAuP bond angle is appreciably bent [170.07(11) (9), 171.22(8)8 (10)]. # 2002 Elsevier Science B.V.
