The stereochemistry of N-acyl/N-sulfonyl 5H-dibenzo[b,d]azepin-7(6H)-ones (I, II) was examined in detail by freezing the conformation with a methyl group at the C-4 of dibenzoazepine. Because the two axes (axis 1, axis 2) move together concertedly, I and
Chemoselective Synthesis of N-arylbenzamides and Benzoyloxyacetanilides from Aryl Isocyanides: Styrene as Aryl and Arylcarboxymethylene Source

Styrenes serve as unique aryl or arylcarboxymethylene source towards aryl isocyanides in the presence of Cu(II)/TBHP, and yield N-arylbenzamides or benzoyloxyacetanilides respectively. The chemoselectivity of the reaction is controlled by the nature of the substituents present on styrene ring. Whereas styrenes substituted with electron-releasing alkyl and alkoxy groups yield N-arylbenzamides, unsubstituted styrene and those with electron-withdrawing substituents furnish benzoyloxyacetanilides as the major product. With benzylamines as the substrate, N-arylbenzamides are formed exclusively as they act only as an aryl donor. TBHP serves as a promoter and oxygen source. Both the pathways are believed to proceed through an initial oxidative C?C bond cleavage of styrene. (Figure presented.).

Two routes to phenanthridines are reported; a palladium-mediated route using imidoyl-selanides as precursors and a modified radical route using aryl imines as starting materials. ARKAT-USA, Inc.

Imidoyl phenyl selenides have been shown to be precursors to phenanthridines, when treated with Pd(PPh3)4 under reflux in toluene in the presence of a base, giving reasonable yields. It is proposed that insertion of palladium into th
