{ALFA} Reducing agent. Converts vic-dihalides and epoxides to alkenes, and ɑ-haloketones to ketones: J. Am. Chem. Soc., 82, 3399, 3696 (1960), reduces benzoquinones to hydroquinones: J. Chem. Soc. (C), 2349 (1969), and deoxygenates aromatic amine oxides: Chem. Pharm. Bull., 24, 1839 (1976). Alkyl nitro compounds are reduced to oximes: J. Chem. Soc. (C), 1182 (1970); Synthesis, 7 (1974). Aromatic nitro groups can be selectively reduced in DMF under mild conditions to arylamines, applicable to solid supported systems: Tetrahedron Lett., 40, 245 (1999).

{ALFA} With vinyl halides, forms vinyl Cr compounds which can add selectively to aldehydes to give allylic alcohols (Nozaki reaction): Tetrahedron Lett., 24, 5281 (1983). Better results have been obtained in the presence of a trace of NiCl2: J. Am. Chem. Soc., 108, 6048 (1986). For similar reaction with alkynyl halides, see: Tetrahedron Lett., 26, 5585 (1985); Tetrahedron Lett., 28, 3

{ALFA} Promotes the addition of allylic halides to aldehydes to give homoallylic alcohols, generally with high anti- selectivity (Hiyama reaction): Tetrahedron Lett., 22, 1037 (1981); 23, 2343 (1982); Tetrahedron, 37, 3873 (1981); J. Am. Chem. Soc., 113, 4218 (1991).

Intramolecular application of the Nozaki reaction has effected closure of a 13-membered ring: J. Am. Chem. Soc., 110, 5198 (1988), and of a strained 9-membered ring: J. Am. Chem. Soc., 112, 5369 (1992), in good yield. For brief reviews of CrCl2 as a reagent, see: J. Prakt. Chem./ Chem.-Ztg., 338, 491 (1996); Synlett, 722 (2001).
