- The direct electrochemical synthesis of phenylselenolato complexes of some main group and late transition elements
-
The electrochemical oxidation of anodes of selected Main Group or late transition metals (M) in non-aqueous solutions of diphenyl diselenide gives the corresponding M(SePh)n compounds in high yields (M=Zn, Cd, n=2; M=Cu, Ag, Tl, n=1; M=Sn, n=4)

- Reactions of Some Main Group Metals with Diphenyl Disulphide and Diphenyl Diselenide
-
Indium reacts with both Ph2S2 and Ph2Se2 in refluxing toluene to give the compounds In(EPh)3 (E = S or Se) in high yield.Under similar conditions tin gives Sn(EPh)4.Thallium reacts with Ph2Se2 to form Tl(SePh), but does not react with Ph2S2.Neither zinc nor gallium reacts with Ph2S2 or Ph2Se2.With mixtures of Ph2E2 and I2, indium yields the previously unreported InI(EPh)2 compounds.The reactions of In(SePh)3 are those of a typical indium(III) Lewis acid.Possible factors affecting the reactions of metals with Ph2S2 or Ph2Se2 are briefly discussed.

- Substitution Reactions of Thallous Thiophenoxide and Thallous Phenylselenide with Halogen-Bearing Substrates
-
Thallous thiophenoxide (1) and thallous selenide (2) were prepared by the action of either thallous ethoxide or thallous pentoxide on thiophenol and benzeneselenol.The reagents 1 and 2 reacted readily with aroyl and acyl halides, imidoyl chlorides, α-halo ketones, α-halo esters, α-halo lactones, α-halo carboxylic acids, allyl halides, alkyl halides, chlorotrimethylsilane, chloroacetonitrile, and N-chlorosuccinimide to give substitution products and varying amounts of diphenyl disulfide and diphenyl diselenide.The reactions were run as heterogeneous mixtures in ether.The origin of the diphenyl disulfide and diphenyl diselenide was homolytic cleavage of the thallium-sulfur or thallium-selenium bond, on the basis of the products derived from the reactions of N-chlorosuccinimide with 1 and 2.
