PRODUCT INTRODUCTION

Description

Potassium tert-butoxide is a strong nonnucleophilic base. It is used in various chemical reactions such as catalysis, dehydrohalogenation, amidation of esters and Mizoroki-Heck type reactions. It is also used as an initiator in the anionic polymerisation of carbazole-substituted ethylene oxide. In addition, it catalyses the reaction of hydrosilanes and heterocyclic compounds to produce silane derivatives and hydrogen.
