The reaction of olefins with a mixture of phenylselenenyl chloride and mercury (I1) thiocyanate in benzene as the solvent affords@-(phenylse1eno) alkyl isothiocyanates selectively in good to excellent yields. The mercury salt not only increases the N selectivity in a kinetically controlled reaction but also accelerates the isomerization of@-(phenylseleno) alkyl thiocyanates to the corresponding isothiocyanates. Oxidative elimination of the (3-( ...
