Supported gold nanoparticles, prepared by deposition of acetone solvated Au atoms on supports as carbon and c-Al2O3, behave as valuable catalysts for the regioselective hydrosilylation of 1-hexyne with different silanes. The catalytic behaviour of gold-based systems is compared with the activity of supported platinum catalysts and a different affinity between the metals and the silanes is observed.

Abstract
Supported gold nanoparticles, prepared by deposition of acetone solvated Au atoms on supports as carbon and c-Al2O3, behave as valuable catalysts for the regioselective hydrosilylation of 1-hexyne with different silanes. The catalytic behaviour of gold-based systems is compared with the activity of supported platinum catalysts and a different affinity between the metals and the silanes is observed.
