Alkyl halides and tosylates are reduced with CrCl2 in the presence of a catalytic amount of vitamin B12 or cobalt phthalocyanine to give alkylchromium reagents, which add to aldehydes without affecting the coexisting ketone or ester groups.

The lithium salts of trityl- and diphenyl-4-pyridylmethyl-hydrazones of both aldehydes and ketones react with electrophiles (alkyl halides, aldehydes, ketones, crotonates) at low temperature to form C-trapped azo compounds; these intermediates decompose homolytically with loss of nitrogen below room temperature and can be diverted in a synthetically useful way to alkanes, alkenes, alcohols or saturated esters.
