The role of stereoelectroniceffects in the electrochemical oxidation of arylselenides Se-substituted by a trimethylsilylmethyl group and those with substituents bearing a carbonyl group have been considered. Although the HOMO of these compounds is formed of pz-type electrons of the ArSe moiety, the predominant contribution from the lone pair of Se makes the heteroatom more susceptible to direct electronic
The reaction of phenylselenenyl chloride with olefins in acetonitrile in the presence of an acid catalyst and water is a convenient method for the aminoselenation of olefins.

AbstractA novel route to 2,2‐diarylvinyl phenyl selenides is reported by dehydration of the corresponding 2,2‐diaryl‐2‐hydroxyethyl phenyl selenides, prepared by oxyphenylselenenylations of the corresponding 1,1‐diarylethylenes, upon treatment with p‐toluenesulfonic acid.
