A new electrochemical procedure for the electrocatalytic reduction of benzaldehyde in ionic liquid,1-butyl-3-methyllimidazoliumtetrafluoborate (BMIMBF4),to phenylmethanol was investigated for the first time.The experiment was carried out in undivided cell under mild conditions,and the use of volatile and toxic solvents and catalysts,as well as any other additional supporting electrolytes,was avoided.The electrochemical reduction behavior of benzaldehyde in BMIMBF4 had been studied by cyclic voltammetry with a reduction peak at -1.8 V (vs.Ag).Phenylmethanol was obtained with 70% yield and 100% selectivity,by typical electrolyse procedure.

Key words: electrocatalytic reduction, ionic liquid, benzaldehyde, phenylmethanol
