Sodium dithionite is an inexpensive reagent that reduces aldehydes to primary alkanols 61 under aqueous conditions (Table 20, entries 1, 2).[‌610‌,‌611‌] Aldehydes have also been reduced with hydrogen selenide under photolysis (entries 3, 4),[‌612‌] hydrogen telluride (entries 5, 6),[‌613‌] sodium sulfide,[‌614‌] sodium telluride (entry 7),[‌615‌] and the lithium enolate of acetaldehyde (generated in situ from the action of butyllithium on tetrahydrofuran).[‌616‌] Whilst the efficiency of some of these reactions is relatively high, these methods have only rarely been used in synthesis.
