N2 - Reactions between HC=CC=CSiMe3 and several ruthenium halide precursors have given the complexes Ru(C=CC=CSiMe3)(L-2) Cp' [Cp' = Cp, L = CO (1), PPh3 (2); Cp' = Cp*, L-2 = dppe (3)]. Proto-desilylation of 2 and 3 have given unsubstituted buta-1,3-diyn-1-yl complexes Ru(C=CC=CH)(L-2) Cp' [Cp' = Cp, L = PPh3 (5); Cp' = Cp*, L-2 = dppe (6)]. Replacement of H in 5 or 6 with Au(PR3) groups was achieved in reactions with AuCl(PR3) in the presence of KN(SiMe3)(2) to give Ru(C=CC=CAu(PR3)}(L-2) Cp' [Cp' = Cp, L = PPh3, R = Ph (7); Cp' = Cp*, L-2 = dppe, R = Ph (8), tol (9)]. The asymmetrically end-capped {Cp(Ph3P)(2)Ru} C=CC=C{Ru(dppe) Cp*} (10) was obtained from Ru(C=CC=CH)(dppe) Cp* and RuCl(PPh3)(2)Cp. Single-crystal X-ray structural determinations of 1 - 3 and 6 - 9 are reported, with a comparative determination of the structure of Fe(C=CC=CSiMe3)(dppe) Cp* (4), and those of a fifth polymorph of {Ru(PPh3)(2)Cp}(2)(mu-C=CC=C) (12), and {Ru(dppe) Cp}(2)(mu-C=CC=C) (13).
