The reactivity of mesomeric carbanions derived from allylphosphine-boranes varies as a function of electrophile. Small sp 3 -electrophiles react predominantly at the carbon atom whereas bulky sp 3 -electrophiles and carbonyl compounds react mainly at the carbon. In the case of electrondeficient aldehydes reduction of carbonyl group and formation of the corresponding alcohols is observed. This is attributed
