In addition to the parent compounds, nine methyl-substituted 1,2-dihydro-4H-3,1-benzoxazines with and without N-methyl substitution were prepared.The chain tautomer could only be detected in the case of 1,2-dihydro-2-(p-nitrophenyl)-4H-3,1-benzoxazine in
Iridium-catalyzed regioselective silylation of aromatic and benzylic C-H bonds directed by a secondary amine

Reported herein is an iridium-catalyzed, regioselective silylation of the aromatic C-H bonds of benzylamines and the benzylic C-H bonds of 2,N-dialkylanilines. In this process, (hydrido)silyl amines, generated in situ by dehydrogenative coupling of benzylamine or aniline with diethylsilane, undergo selective silylation at the C-H bond γ to the amino group. The products of this silylation are suitable for subsequent oxidation, halogenation, and cross-coupling reactions to deliver benzylamine and arylamine derivatives.
