The reaction of thioacetals of phenyl ketones, α,α-bis(trimethylsilyl)alkyl sulfides, and 2-alkyl-2-ethylthioalkanenitriles with tributylstannyllithium gave the corresponding α-anions of sulfides, α,α-bis(trimethylsilyl)alkane, and nitriles, respectively.

Nanolayered cobalt–molybdenum sulphide (Co–Mo–S) materials have been established as excellent catalysts for C–S bond construction. These catalysts allow for the preparation of a broad range of thioethers in good to excellent yields from structurally diverse thiols and readily available primary as well as secondary alcohols. Chemoselectivity in the presence of sensitive groups such as double bonds,

[reaction: see text] Radicalcations of tert-alkyl phenyl sulfides 1-4 have been generated photochemically in MeCN in the presence of the N-methoxyphenanthridinium cation (MeOP(+)), and the rates of C-S bondcleavage have been determined by laser flash photolysis.

that anion 3 is produced. Related examples from the literature are compiled. A suggested mechanism involves a single electron transfer from the generated cumyllithium (3) to the cumyl phenyl sulfide (1S) leading to thiophenoxide anion and two cumyl radicals, which mainly couple in a solvent cage. Such a thiophenoxide displacement by anion 3 has been demonstrated experimentally. Para tert-butyl groups

Alcohols, ethers, and esters were directly converted to the corresponding alkyl phenyl selenides by the reaction of diphenyldiselenide and the La/Me3SiCl/cat.I2/cat.CuI. It was suggested that alkyl phenyl selenides were formed by the SH2 type reaction of diphenyldiselenide with alkyl radicals generated from alcohols, ethers or esters.
