Ba[CH(SiMe 3 ) 2 ] 2 (THF) 3 catalyzes the fast and controlled dehydrogenative polymerization of Ph 2 SiH 2 and p ‐xylylenediamine to afford polycarbosilazanes. The structure (cyclic versus linear; end‐groups) and molecular weight of the macromolecules can be tuned by adjusting the Ph 2 SiH 2 /diamine feed ratio. A detailed analysis of the resulting materials (mol. wt up to ca. 10 000 g mol −1 ) is provided.
