Phase-Transfer Catalyzed Alkylation and Cycloalkylation of 3-Substituted-1H-pyrazol-2-in-5-ones in the Absence or Presence of Carbon Disulphide
Ali Khalil Ali;
Abstract
PTC-alkylation of 3-substituted-1H-pyrazol-2-in-5-ones by different organohalogen reagents at 25°C 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. Copyright © Taylor & Francis Inc.
