Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Find details here.

Zirconocene dichloride serves as a catalyst, enabling efficient synthesis of pyrrole with high yields and simplifies the purification process economically.

Application

Useful in the synthesis of a wide range of early-transition-metal complexes and organometallic compounds.

Used to promote greener amidations of carboxylic acids and amines in catalytic amounts. This technology avoids the requirement of preactivation of the carboxylic acid or use of coupling reagents.

Direct amide formation from unactivated carboxylic acids and amines
