Abstract
A combination of PhICl2 and Pb(SCN)(2) is effective for the p-selectiv e thiocyanation of various types of p-unsubstituted phenols and naphth ols 1 to give p-thiocyanatophenols and naphthols 3. The reaction proce eded at 0 degrees C to room temperature in good to quantitative yields , Twenty-five examples are given, in which various functional groups, such as chloro, allyl, carbonyl, ester, amide, and primary hydroxyl gr oups, are shown to be compatible with this reaction.
