convenient procedure for the synthesis of homoallylic alcohols from carbonyl compounds and allylboranes is described. Allyl-, 2-methylallyl-, crotyl- and 3,3-dimethylallyl(dialkyl)boranes, as well as diallyl(alkyl)boranes and derivatives of 3-allyl- and 3-metallyl-3-borabicyclo[3.3.1]non-6-ene are effective reagents for allylation of carbonyl compounds (aldehydes, ketones, esters, carboxylic acids and others)
