Hydride abstraction from the gold (disilyl)ethylacetylide complex [(P)Au{η(1) -C≡CSi(Me)2CH2CH2SiMe2H}] (P=P(tBu)2o-biphenyl) with triphenylcarbenium tetrakis(pentafluorophenyl)borate at -20 °C formed the cationic gold (β,β-disilyl)vinylidene complex [(P)Au=C=CSi(Me)2CH2CH2Si(Me)2](+)B(C6F5)4(-) with ≥90% selectivity. (29)Si NMR analysis of this complex… CONTINUE READING
