Synthesis of Benzimidazoles Containing a Fused Alicyclic Ring By Rhodium - Catalysed Hydroformylation of N-Alkenyl-1,2-diaminobenzenes

Rhodium-catalysed reactions of N-alkenyl-1,2-diaminobenzenes (3) with hydrogen and carbon monoxide give benzimidazoles containing a fused alicyclic ring ((8) and (9)) in excellent yields.In some cases intermediate bicyclic compounds can be isolated and the 1H and 13C n.m.r. spectra of one of these, the 3,4,5,6-tetrahydro-4-methyl-3H-1,6-benzodiazocine (6), shows evidence for unusual atropisomerism.

2H-Benzimidazoles (Isobenzimidazoles). Part 3. Thermal Isomerisation of Substituted 2H-Benzimidazoles to 1H-Benzimidazoles

2H-Benzimidazole-2-spirocyclohexanes (1) when heated undergo a 1,5-sigmatropic rearrangement to 2,3-disubstituted 1H-benzimidazoles.A decided effect on the direction of this isomerisation was observed with substituents in the homodiene ring.
