A mild, highly regio- and stereoselective method for the crotylation of aldehydes and ketones mediated/catalyzed by titanocene(III) is described. Optimized conditions permit the selective generation of gamma-adducts in high yields together with high stereoselectivity, with a predominance of anti stereoisomers.
