A homologous series of alkynyl chalcoether complexes: [W(η 2 - i PrEC≡CPh)(CO) 2 (Tp*)]BF 4 (E = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazol-1-yl)borate)

Caldwell, Lorraine; Hill, Anthony; Willis, Anthony

Description

The first complete set of homologous alkynyl chalcoether complexes, isolated as the structurally characterized salts [W(η2-iPrECtriple bond; length of mdashCPh)(CO)2(Tp*)]BF4 (A = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazolyl)borate), result from the reactions of the free alkynes iPrECtriple bond; length of mdashCPh with [WI(CO)3(Tp*)] in the presence of AgBF4. The neutral complex [W(η2-iPrSeCtriple bond; length of mdashCPh)Cl(CO)(Tp*)] is obtained from the reaction of [W(η2-iPrSeCtriple...[Show more]

dc.description.abstractThe first complete set of homologous alkynyl chalcoether complexes, isolated as the structurally characterized salts [W(η2-iPrECtriple bond; length of mdashCPh)(CO)2(Tp*)]BF4 (A = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazolyl)borate), result from the reactions of the free alkynes iPrECtriple bond; length of mdashCPh with [WI(CO)3(Tp*)] in the presence of AgBF4. The neutral complex [W(η2-iPrSeCtriple bond; length of mdashCPh)Cl(CO)(Tp*)] is obtained from the reaction of [W(η2-iPrSeCtriple bond; length of mdashCPh)(CO)2(Tp*)]BF4 with [nBu4N]Cl and co-exists in two forms in solution as a result of slow rotational isomerism of the alkyne. Depending on the choice of solvent, either pure rotamer may be crystallised.
