摘要

5, 5-Methylene-bis (benzotriazole)(2) is a versatile intermediate in the preparation of several metal passivators1 and light-sensitive materials. 2 Though it is a useful molecule, a review of the literature, including patents, indicated the absence of an easily performed synthesis. As part of our research program on the study of green chemistry, 3 we have developed a practical pilot-scale method for the preparation of 5, 5-methylene-bis (benzotriazole) from ...
