1. Reduces aromatic aldehydes to symmetrical epoxides in good yield: J. Am. Chem. Soc., 85, 1884 (1963). Both cis- and trans-isomers are formed. For list of examples, see: Org. Synth. Coll., 5, 358 (1973). Under suitable conditions, reaction of the intermediate with a second aldehyde can lead to mixed deoxybenzoins or diaryl enamines: Synthesis, 225 (1991).
2. Has also been used for a variety of other reductions including that of ozonolysis intermediates: Helv. Chim. Acta, 50, 2387 (1967), and of primary alkyl nitro compounds to nitriles: Synthesis, 36 (1979). Bromohydrins can be converted to alkenes, by reductive elimination from their triflate esters: J. Am. Chem. Soc., 102, 1433 (1980):
3. Reacts with BrCCl₃ to give dichloromethylenephosphorane Cl₂C=PPh₃, which undergoes Wittig reaction with aldehydes to give 1,1-dichloroalkenes, giving better results than the CCl₄/PPh₃ combination: Tetrahedron Lett., 1237, 1239 (1977); Synthesis, 554 (1980). Similarly, with Br₂CF₂, the CF₂ group can be transferred to both aldehydes and ketones: J. Fluorine Chem., 1, 123 (1971); Synth. Commun., 3, 197 (1973).
