  The synthesis and reactions of the novel bis(diphenylacetylene) complex [WI2(NCMe)2(η2-PhC2Ph)2]

  摘要：

  The mono(acetonitrile) compound [WI2(CO)(NCMe)(eta-2-PhC2Ph)2] reacts in refluxing acetonitrile for 5 h in the presence of PhC2Ph to give the bis(acetonitrile) compound [WI2(NCMe)2(eta-2-PhC2Ph)2] (1) in high yield. Refluxing 1 in CHCl3 for 3 h affords the iodo-bridged dimer [W(mu-I)I(NCMe)(eta-2-PhC2Ph)2]2 (2). Compound 1 reacts with one equivalent and three equivalents of PPh3 to give [WI2(NCMe)(PPh3)(eta-2-PhC2Ph)2] (3) and [WI2(PPh3)3(eta-2-PhC2Ph)] (4), respectively. Equimolar quantities of 1 and Ph2P(CH2)nPPh2 (n = 1-3) react in CH2Cl2 at room temperature to give the acetonitrile displaced products [WI2{Ph2P(CH2)nPPh2}(eta-2-PhC2Ph)2] (5-7). Reaction of 1 with an equimolar amount of Na[S2CX] (X = NMe2 or NEt2) in CH2Cl2/MeOH 50:50 gives the iodo-bridged dimers [W(mu-I)(S2CX)(eta-2-PhC2Ph)2]2 (8 and 9). Two equivalents of Na[S2CX] (X = NMe2 or NEt2) react in CH2-Cl2/MeOH 50:50 at room temperature to afford the bis(dithiocarbamate) compounds [W(S2-CX)2(eta-2-PhC2Ph)2] (10 and 11). C-13 NMR spectroscopy suggests that the two diphenylacetylene ligands in [W(S2CX)2(eta-2-PhC2Ph)2] are donating a total of six electrons to the metal.
