Abstract
Desilylation of [W(≡CC≡CSiMe3)(CO)2L] (L = HB(pz)3, HB(pz′)3; pz = pyrazol-1-yl, pz′ =3,5-dimethylpyrazol-l-yl) with [Bu4N]F in the presence of [AuCl(PPh3)] provides the neutral complexes [W(≡CC≡ CAuPPh3)(CO)2L] in addition to traces of the salt [Bu 4N] [Au(C≡CC≡ W(CO)2{HB(pz)3}) 2]. The corresponding salt [N(PPh3)2] [Au(C≡CC≡W(CO)2{HB(pz′)3})2] may be obtained in high yield via the reaction of [W(≡CC≡CSiMe 3)(CO)2{HB(pz′)3}] with methanolic KOH in the presence of [AuCl(SMe2)].
