| Popis: | Equimolar quantities of [WI(CO)(NCMe){P(OiPr)3}2(η2-MeC2Me)][BPh4] and L {L=NCEt, NCiPr, NCtBu, NCPh, NCCH2Ph, 1,2-C6H4(NCCH2)2, NCCH2(C4H3S-3)} react in CH2Cl2 at room temperature to give the nitrile exchanged products, [WI(CO)L{P(OiPr)3}2(η2-MeC2Me)][BPh4] (1–7). The complexes for L=NCiPr (2), NCtBu (3), NCCH2Ph (5), and 1,2-C6H4(NCCH2)2 (6) have all been crystallographically characterised. The geometry of all four complexes is psuedo-octahedral with the alkyne ligand occupying one site trans- to an iodo ligand, with the triisopropylphosphite ligand mutually trans and the carbonyl ligand trans to the nitrile group. |
