Intermolecular additions of the O-H bonds of phenols and alcohols and the N-H bonds of sulfonamides and benzamide to olefins catalyzedby 1 mol % of triflic acid and studies to define the relationship between these reactions and those catalyzed by metal triflates are reported.Cyclization of an alcohol containing pendant monosubstituted and trisubstituted olefins catalyzed by either triflic acid or metal triflates formproducts from addition to the more substituted olefin, and additions of tosylamide catalyzed by triflic acid or metal triflates form indistinguishableratios of the two N-alkyl sulfonamides.
