A novel photoinducedreduction of group 16 heteroatom compounds such as organic selenides, tosylates, and tellurides has been developed. In particular, organic selenides, which can not be reduced with Sml2 in the dark (or even in the presence of HMPA), undergo reductive cleavage efficiently by using the Sml2-hv system.

α-Aminocarbanionequivalents (NH2) and α-hydrazino anionequivalents (NHNH2) are readily accessible from the C-alkylation products of t-butyldiphenylmethylhydrazones; these azoalkanes can be efficiently transformed into amines, hydrazines, and also alkanes under mild reaction conditions.
A novel photoinduced reduction system of low-valent samarium species: reduction of organic halides and chalcogenides, and its application to carbonylation with carbon monoxide
irradiation is found to enhance the reducing ability of samariumdiiodide (SmI2) dramatically. Organic halides (RCl, RBr, RI) and chalcogenides (RSPh, RSePh, RTePh) are smoothly reduced to the corresponding hydrocarbons by using this SmI2–hv system. The photoactivation can be also applied to ytterbium diiodide (YbI2) successfully. When the reduction of alkyl chlorides (RCl) by using the SmI2–hv system is conducted
