Acylation of terminal alkynes with N-acylbenzotriazole: synthesis of conjugated ynones in ionic liquids
1-Butyl-3-methylimidazolium tetra-fluoroborate ([BMIM][BF 4 ]) has been used as an ionic liquid for the synthesis of conjugated ynones in good yields from alkyl/aryl N -acylbenzotriazoles and terminal alkynes in catalytic amounts of zinc chloride. Mild reaction conditions, short reaction time, and e...
