bond formationreactions via acylnitrene transfer have recently attracted much attention, but direct detection of the proposed acylnitrenoid/acylimido M(NCOR) (R=aryl or alkyl) species in these reactions poses a formidable challenge. Herein, we report on Ru(NCOR) intermediates in C−N bond formation catalyzed by [RuIV(Por)Cl2]/N3COR, a catalytic method applicable to aziridine/oxazoline formation from

Au(III)-catalyzed intermolecular amidations of benzylic C–H bonds with sulfonamides and carboxamides are described. The protocol with the Au–bipy complex/N-bromosuccinimide system provides practical applications for synthesis of various amides via C–H activations. The reaction proceeds with high efficiency to give the corresponding amines, which are extremely useful synthetic intermediates.
This invention provides certain benzamide derivatives of the formula: ##STR1## wherein Z is bond, --CH.sub.2 --, or CHCH.sub.3 ; A is --CH.sub.2 --, or CH.sub.2 CH.sub.2 --; and represents a single or double bond; and their pharmaceutical formulations and their use as anticonvulsant agents.
