Abstract
Some novel gold(I) derivatives of the type [LAuCl] (L = DIC, PPh3, NHCs) have been synthesized and char- acterized. The products of the transmetalation reaction between these species and tributyl-phenylethy- nylstannane have been isolated and characterized. An exhaustive kinetic study on the transmetalation reaction has also been carried out in CHCl3 and CH3CN. The experimental results were discussed in terms of the electronic and steric characteristics of the ligands and an interpretation of the peculiar influence of different solvents on the reaction rates was proposed.File in questo prodotto:
