Radical Substitution

The photolysis of sulfur monochloride with a series of saturated aliphatic hydrocarbons yielded alkyl chlorides, di- and polysulfides, hydrogen chloride, and elemental sulfur. The free radical substitution reactions leading to the production of alkyl chloride and the di- and polysulfides were shown to proceed via a chlorine atom abstraction reaction. The major products, the di- and polysulfides could be transformed quantitatively, by lithium aluminum hydride reduction into their corresponding mercaptans. The reaction describes a simple free radical route to the synthesis of a variety of alkyl mercaptans.

Abstract An efficient preparation was developed for 3,3',4,4'-tetrachloroazobenzene and the corresponding azoxy and hydrazo derivatives, based on the lithium aluminum hydride reduction of 3,4-dichIoronitrobenzene. Batches were analyzed for purity by using a reverse phase high pressure liquid chromatographic method. All 3 compounds can be synthesized in gram quantities with 97–99% purity. Detailed mass, infrared, and nuclear magnetic resonance spectral analyses are presented.
