Abstract
1-Alkylbenzimidazoles and 1-benzylbenzimidazole react with phenylsodium to form the corresponding 2-sodio derivatives. 5-Bromo-1-ethylbenzimidazole does not react with phenyl- and amylsodium. The metallation of 1-arylbenzimidazoles with phenylsodium is appreciably complicated by side processes. A path for the preparation of 2-sodio-1-arylbenzimidazoles from 1-arylbenzimidazoles and o-anisylsodium is proposed. Some transformations of the organosodium compounds of N-substituted benzimidazoles were studied.
