**3.1 Gadolinium(III) chloride: a novel and an efficient reagent for the synthesis of homoallylic alcohols**

Carbonyl compounds efficiently undergo nucleophilic addition reactions with allylstannanes in the presence of GdCl3.H2O in acetonitrile under extremely mild reaction conditions to give the corresponding homoallylic alcohols in excellent yields and with high chemoselectivity (**Figures 9**–**11**) [15].
