Abstract : Preparation of [WCl2(CO)(3)(NCMe)(2)] by reacting of [WI2(CO)(3)(NCMe)(2)] with two equivalents of NaCl in acetone, followed with an excess of EtC2Me (2-pentyne) in CH2Cl2 gives the 2-pentyne complex [WCl2(CO)(NCMe)(eta(2)-EtC2Me)(2)] (1). Equimolar quantities of 1 with (L = NPh3 and PPh3) react in CH2Cl2 to give the acetonitrile replaced products, [WCl2(CO)(PPh3) (eta(2)-EtC2Me)(2)] (2) and [WCl2(CO)(NPh3)(eta(2)-EtC2Me)(2)] (3) in good yield. Reaction of 1 with equimolar amount of bidentate of {L-2 = Ph2P(CH2)(n)PPn(2) (n = 1-5)} in CH2Cl2 at room temperature afforded the mono-(2-Pentyne) complexes, [WCl2(CO)(Ph2P(CH2)(n) PPh2)(eta(2)-EtC2Me)] (n = 1-5) (4-8).
