Sulfuryl chloride has been shown to be useful activator for sulfides in the selective preparation of ortho-alkylated phenolsvia [2,3]sigmatropicrearrangement. By this process, ortho-alkylated phenols have been prepared with various symmetric sulfides in good yields. The rearrangement products having 3-chloropropyl or 3-methyl-3-butenyl moiety have been converted into 2H-1-benzopyran derivatives.
