ABSTRACT:
Cyclotrisilazanes, including hexamethylcyclotrisilazane, a difunctional blocking agent used to derivatize and protect active hydrogen-containing substrates during chemical analysis and synthetic reactions, may be prepared by heating cyclotetrasilazanes using a Group VIII catalyst in the presence of hydrogen. In addition, the average degree of polymerization of cyclosilazane compositions may be reduced.
