Abstract

Herein, we present the first efficient and sustainable multicomponent synthesis (MCS) of 2-pyrazolines using acceptorless dehydrogenation of benzyl alcohols catalysed by nickel(II) catalysts. Two air-stable phosphine free nickel(II) complexes anchored by NNN-type pincer ligands were synthesized and efficiently used in the MCS of 40 distinct pyrazoline derivatives.
