N2  - Reactions between W(CCC&#197;&#8801;CH)(CO)3Cp (1) and &#123;Mo(CO)2Cp&#125;2,Pt (&#951;-C2H4)(PPh3)2 and 1,4-I2C6H4 &#91;the latter catalysed by Pd0/CuI&#93; have given M2&#123;&#956;-HC2C&#197;&#8801;C&#91;W(CO)33Cp&#93;&#125;(CO)4Cp2(2), Pt&#123;&#951;2-HC2C&#197;&#8801;C&#91;W(CO)3-Cp&#93;&#125;(PPh3)2 (3) and 1,4-&#123;&#91;W(CO)3Cp&#93;C&#197;&#8801;CC&#197;&#8801;C&#125;2C6H4 (5), respectively. The adduct Co2&#123;&#956;-PhC2C&#197;&#8801;C&#91;W(CO)3-Cp&#93;&#125;(&#956;-dppm)(CO)4(6) was obtained from W(C&#197;&#8801;CC&#197;&#8801;CPh)(CO)3Cp (4) and Co2(&#956;-dppm)(CO)6. Substitution of one CO ligand in W(C&#197;&#8801;CC&#197;&#8801;CSiMe3)(CO)3Cp (7), prepared from the CuI-catalysed reaction of WCl(CO)3Cp with HC&#197;&#8801;CC&#197;&#8801;CSiMe3in tetrahydrofuran/NHEt2, by bis(diphenylphosphino)methane/Me3NO gave W(C&#197;&#8801;CC&#197;&#8801;CSiMe3)(CO)2(dppm-P)Cp (8). Treatment of (7) with RuCl(PPh3)2Cp afforded &#123;Cp(OC)3W&#125;C&#197;&#8801;CC&#197;&#8801;C-&#123;Ru(PPh3)2Cp&#125; (9), which reacts at the W&#8211;C&#197;&#8801;C&#8211; triple bond with tetracyanoethylene (tcne) to give&#123;Cp(OC)33W&#125;&#123;C&#91;=C(CN)2&#93;C&#91;=C(CN)2&#93;C&#197;&#8801;C&#125;&#123;Ru(PPh3)2Cp&#125; (10), and with Fe2(CO)9 to form the cluster Fe22W&#123;&#956;3-C2C&#197;&#8801;C&#91;Ru(PPh3)Cp&#93;&#125;(CO)8Cp (11). The molecular structures of (1), (2), (6), (8), (10) and (11) have been determined by single-crystal X-ray diffraction.
