A convenient procedure for the preparation of organic selenides

Treatment of diphenyl diselenide with tributylphosphine in an alkaline medium forms phenylselenolate ion which converts alkyl halides, α,β-unsaturated ketones, and epoxides into alkyl selenides, (phenylseleno)alkenones, and β-(phenylseleno)alkanols, respe

Synthetic utility of 1,1,2,2-tetraaryIdisilanes: Radical reduction of alkyl phenyl chalcogenides

Reactivity of tetraaryldisilanes as radical reducing agents of alkyl phenyl chalcogenides initiated by Et3B or AIBN was studied. Here, the reactivity of alkyl sulfide was poor; however, various alkyl phenyl selenides and tellurides were reduced to the corresponding hydrocarbons in good yields with 1,1,2,2-tetraphenyldisilane.

77Se, 13C and 1H NMR Spectra of Phenylselenenylcycloalkanes, -cycloalkenes and Some of Their Selenoxides and 125Te NMR of a Tellurium Analogue

The 77Se, 13C and 1H NMR spectra of 46 mostly new compounds with phenylselenenyl groups attached to carbocycles and of three new corresponding selenoxides and the 125Te NMR of phenyltellurenylcyclohexane are reported.Substituent effects on the chemical sh
