PRODUCT INTRODUCTION
description
The three nitrogen atoms make diethylenetriamine (DETA) an excellent complexing agent for metals such as cobalt, copper, and platinum. Some DETA-based metal complexes can be used to catalyze organic reactions; examples are the oxidation of phenol with hydrogen peroxide and Heck cross-coupling reactions.
