The use of potassium alkynyltrifluoroborates in Mannich reactions
摘要:
Potassium alkynyltrifluoroborates react with amines and salicylaldehydes in the presence of benzoic acid to generate highly functionalized amines. Ionic liquids such as butylmethylimidazolium tetrafluoroborate (BmimBF(4)) are suitable solvents for the reaction. (C) 2003 Elsevier Ltd. All rights reserved.
