  Conversion of alkynes and nitriles into organo and organonitrogenated species at group VI and VII dinitrogen-binding metal centers. Synthesis of some vinylidene and alkynyl complexes of rhenium

  摘要：

  The reactions of phenylacetylene and other alkynes [HC-=CCH2OH, HC=-C(CH2)2OH, HC=-CCH2CMe2CH2COCH3, HC=CSiMe3 and MeC=-CSiMe3], in the presence of acetonitrile or benzonitrile, with the following complexes have been investigated usually at room temperature: trans-[Mo(N2)2L4] (L = PMe2Ph), cis-[Mo(N2)2(PMePh2)4], cis-[W(N2)2L4], trans-[ReCl(N2)L4], mer-[ReC](N2)(PPh3)L3'] {L' = P(OMe)3}, [ReCl2(N2COPh)L3'] and [(eta5-MeC5H4)Mn(CO)2(NCMe)]. Cyclic trimerization was the main reaction detected for phenylacetylene (except for the Mn complex), although dimers, products of hydrogenation and species derived from alkyne/nitrile coupling were also formed in smaller amounts; for the Mo- or W-systems, the total yields were below ca. 40% relative to the metal, but the Re-systems exhibited a modest catalytic activity. The other alkynes underwent, also in low yields, mainly dimerization, cyclic or linear trimerization, apart from, to a smaller extent, coupling reactions with the nitriles or hydrogenation. The alkynyl complexes [ReCl(C=CPh) {P(O) (OMe)2}(PPh3)L2'] and (ReCl(C=CPh) {P(O)(OMe)2}(NCMe)2L'] were prepared by reaction of mer-[ReCl(N2)(PPh3)L3'] with PhC=CH, in the absence and in the presence of NCMe, respectively, whereas the benzonitrile/dinitrogen complex [ReCl(N2)(CNPh)L3'] was obtained either by reaction of that N2-complex with NCPh or by the reaction of [ReCl2(N2COPh)L3] with NCPh in the presence of NaOMe. The vinylidene compound trans-[Re(CNMe)(C=CHPh)(dppe)2] [BF4] (dppe=Ph2PCH2CH2PPh2) was formed by reaction of trans-[ReCl(CNMe)(dppe)2] with PhC=CH, in the presence of T1[BF4], which did not lead to the formation of detectable amounts of any alkyne-derived organic product.
