Abstract:

The reaction of aldehydes/ketones with homopropargylic alcohols in the presence of 1-n-Butyl-3-methylimidazolium chloroaluminate [bmim]Cl·AlCl3 (N = 0.56-0.67) ionic liquid generates the 4-chloro-5,6-dihydro-2H-pyran derivatives in excellent yield and in short reaction times.

Keywords:

1-n-Butyl-3-methylimidazolium chloroaluminate; aldehydes; ketones; homopropargylic alcohols; 4-chloro-5,6-dihydro-2H-pyran derivatives
