Brønsted Acid-Catalyzed Reactions of Trifluoroborate Salts with Benzhydryl Alcohols Kayla M. Fisher Yuri Bolshan 10.1021/acs.joc.5b02273.s001 https://acs.figshare.com/articles/journal_contribution/Br_nsted_Acid_Catalyzed_Reactions_of_Trifluoroborate_Salts_with_Benzhydryl_Alcohols/2097415 Brønsted acid-catalyzed carbon–carbon bond forming methodology using potassium alkynyl- and alkenyltrifluoroborate salts has been developed. Organotrifluoroborates react with benzhydryl alcohols to afford a broad range of alkynes and alkenes in good to excellent yields. This protocol features good atom economy because organotrifluoroborate salts and alcohols react in a 1:1 ratio. Furthermore, a variety of unprotected functional groups were tolerated under the developed conditions, including amide, aldehyde, free hydroxyl, and carboxylic acid. 2015-12-18 00:00:00 atom economy alkene alkenyltrifluoroborate salts yield organotrifluoroborate salts carboxylic acid ratio benzhydryl alcohols AlcoholsBr methodology Br ønsted aldehyde protocol features Trifluoroborate Salts Benzhydryl potassium alkynyl hydroxyl amide Organotrifluoroborate variety alkyne bond
