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)

structurally characterized salts [W(η2-iPrECCPh)(CO)2(Tp*)]BF4 (A = O, S, Se, Te; Tp* = hydrotris(dimethylpyrazolyl)borate), result from the reactions of the free alkynes iPrECCPh with [WI(CO)3(Tp*)] in the presence of AgBF4. The neutral complex [W(η2-iPrSeCCPh)Cl(CO)(Tp*)] is obtained from the reaction of [W(η2-iPrSeCCPh)(CO)2(Tp*)]BF4 with [nBu4N]Cl and co-exists in two forms in solution as a result
