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

Herbert, John A. L.,Iddon, Brian,Robinson, Andrew G.,Suschitzky, Hans

, p. 991 - 998 (2007/10/02)

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.
