Stable but active zinc catalyst for transesterification

What is it about?

Transesterification is one of the most desirable methods to synthesize functional ester. We developed stable new catalyst for transesterification.

Why is it important?

We report a highly stable but highly active bis(imidazole)/zinc complex as a nontoxic metal catalyst for transesterification reactions. A newly designed zinc complex led to expanded substrate generality and reuse at least five times without loss of activity under an air atmosphere.
