A novel one pot reaction of α,β-unsaturated esters with carbonyls and trimethylsilane gave good yields of β-siloxy esters. This RhCl3 catalyzed method improves upon the two step reaction of silylketeneacetals with carbonyls.

The catalysts [TiCp2(CF3SO3)2] and [ZrCP2(CF3SO3)2THF] are fast and efficient catalysts for the Mukaiyama cross-aldol reaction involving both ketones and aldehydes and the catalysis is promoted by binding of the carbonyl group to the metal after dissociation of triflato ligands.
