Abstract:	Treatment of aliphatic aldehyde with lithium pentamethylcyclopentadienide in the presence of chlorodimethylaluminum provided the corresponding carbinol in excellent yield. The carbinol returns to the parent aldehyde and pentamethylcyclopentadiene by the action of a catalytic amount of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ).

Keywords:	Pentamethylcyclopentadiene Nucleophilic addition Carbon-carbon bond cleavage Chlorodimethylaluminum
