Аннотация:Benzyl alcohols formed by the reduction of benzaldehydes, alkyl aryl ketones, and benzophenones
with sodium tetrahydridoborate in alcohols undergo in situ etherification with the solvent in the presence of
a catalytic amount of HCl. Thus the process may be regarded as one-pot transformation of carbonyl compounds
into the corresponding benzyl alcohols. The yields of ethers depend on the substituent nature in the aromatic
fragment of the initial carbonyl compound and on the alcohol used as reduction medium.
