• CsF promotes the reduction of aldehydes and ketones to alcohols: J. Organomet. Chem., 148, C1 (1978); 172, 143 (1979). Esters can be reduced at elevated temperatures: Synthesis, 558 (1981). Aldehydes and ketones are also reduced in the presence of TBAF: J. Org. Chem., 53, 5415 (1988).

With the same catalyst and a Lewis acid such as zinc chloride, ɑ?-unsaturated aldehydes, ketones and esters are reduced to their saturated counterparts: J. Am. Chem. Soc., 108, 7314 (1986).
• In combination with an equivalent of Titanium(IV) isopropoxide, A13703, a mild, one-pot reduction of tertiary amides to aldehydes can be accomplished in high yield. The initial product is the enamine which can be readily hydrolyzed in situ to the aldehyde: Angew. Chem. Int. Ed., 35, 1515 (1996):
