ABSTRACT |
|
|
|
Green and an efficient procedure for
the synthesis of
2-(5-chloro-3-methyl-1-phenyl-pyrazol-4-yl)-chromen-4-one
derivatives from substituted chalcones in polyethylene glycol-400 as
a green solvent using iodine as a catalyst is reported. The reported
procedure is very practical, short reaction time, and high yielded
over an expensive catalyst. |
