Document Language : Arabic 
Abstract : PTC-alkylation of 3-substituted-1H-pyrazol-2-in-5-ones by different organohalogen reagents at 25degreesC in the presence of tetrabutylammonium bromide as-catalyst was investigated either in the absence or presence of CS2. This work aims to study the comparative reactivity of N-versus O-versus C-alkylation and cycloalkylation.
