1-butyl-3-methylimidazol-2-ylidene as an efficient catalyst for cross-coupling between aromatic aldehydes and N-aroylbenzotriazoles

Cross-coupling of aromatic aldehydes with N-aroylbenzotriazoles in [Bmim]Br in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) provided an efficient procedure for the synthesis of 1,2-diarylethane-1,2-diones.

An efficient general synthesis of 1-(benzotriazol-1-yl)alkyl esters

1-(Benzotriazol-1-yl)alkyl esters 2a-u were obtained in yields averaging 86% by the direct reaction of various aldehydes with the corresponding N- acylbenzotriazoles in the presence of a catalytic amount of potassium carbonate (10-25 mole %). The procedur
