S. Narasimhan et al., CALCIUM BOROHYDRIDE - A REAGENT FOR FACILE CONVERSION OF CARBOXYLIC ESTERS TO ALCOHOLS AND ALDEHYDES, Synthetic communications, 25(11), 1995, pp. 1689-1697
Calcium borohydride reduces both aliphatic and aromatic esters to alco
hols completely in the presence of alkene catalysts. The intermediate
berates formed during the reduction of aromatic esters are converted t
o aldehydes with aqueous NaOCl in good yields.
