29Si NMR spectroscopy was employed to evaluate the electron donor properties of the (L)Au fragments in the cationic gold (β,β‐disilyl)vinylidene complexes [(L)Au=C=CSi(Me)2CH2CH2Si(Me)2]+B(C6F5)4− [L=P(tBu)2o‐biphenyl or NHC] relative to the p‐substituted aryl group in the α‐aryl‐(β,β‐disilyl)vinyl cations [(p‐C6H4X)‐C= CSi(Me)2CH2CH2Si(Me)2]+B(C6F5)4−. Similarly, 19F NMR was employed to evaluate the σ‐ and π‐electron donor properties of the (L)Au fragments in the neutral gold fluorophenyl complexes (L)Au(C6H4F) and in the cationic (fluorophenyl)methoxycarbene complexes [(L)AuC(OMe)(C6H4F)]+SbF6− [L=P(tBu)2o‐biphenyl or IPr] relative to the p‐substituted aryl group of the protonated monofluorobenzophenones [(p‐C6H4X)(C6H4F)COH]+OTf−. The results of these studies indicate that relative to p‐substituted aryl groups, the gold (L)Au fragments [L=P(tBu)2o‐biphenyl or NHC] are significantly more inductively electron donating and are comparable π‐donors and for this reason, the extent of (L)Au→C1 electron donation in gold carbene complexes appears to exceed that provided by a p‐(dimethyamino)phenyl group. Furthermore, the [L=P(tBu)2o‐biphenyl]Au fragment is a nominally stronger electron donor than the (IPr)Au fragment, and both are significantly more inductively electron donating than the (PPh3)Au and [P(OMe)3]Au fragments.
