Abstract
Sulfenylation of electron-rich arenes was carried out with N-unsubstituted sulfenamides in the presence of Brønsted or Lewis acids. α-Methylstyrene as an olefin was also sulfenylated with acidic sulfenamides, and a sulfur substituent was introduced on the methyl group. Intramolecular sulfenylation proceeded for allyl 2-sulfenamoylbenzoate derivatives, and sulfur containing seven-membered heterocycles were obtained.
