Ecofriendly synthesis of a heterogeneous polyvinyl alcohol immobilized copper(ii) Schiff base complex as an efficient, reusable catalyst for the one-pot three-component green preparation of 5-substituted 1H-tetrazoles under mild conditions

Abstract

A new polymeric Cu(ii) Schiff base complex catalyst is developed, which shows high catalytic activity in the preparation of 5-substituted 1H-tetrazoles under mild and green conditions.
