The strength of the self-associated silanol hydrogen bonds were reduced considerably with increased steric hindrance of the substituents. The infrared frequency shifts, as a measure of the strength of the silanol self-association between the free and self-associated silanol hydrogen bonds in the silanol stretching vibration region, were...

Subsequently, Hiittel and co-workers (303, 306, 307) have described a series of gold(I)-olefin complexes involving both cyclic and acyclic mono- and oligoolefins (Table VI). The 1 1 monoolefin complexes, prepared in almost quantitative yield by reaction of excess olefin with AuCl in ether, are monomolecular and are obtained as colorless crystals. The cyclic olefins, which react as well with aqueous HAUCI4 or NaAuC, form complexes which are more stable than those of the corresponding straight-chain olefins. Formation of the complex results in a low infrared frequency shift in the C=C stretching vibration of 115 cm for the...
