Cyclohexanone, a colorless liquid is a cyclic ketone. It is an important building block for the synthesis of a variety of organic compounds. Majority of the cyclohexanone synthesized is utilized as an intermediate in the synthesis of nylon. One of the methods reported for its synthesis is by the palladium catalyzed hydrogenation of phenol.
Mono acyl derivative of o-phenylenediamine is readily converted into the corresponding benzimidazole by the action of heat alone. These conversions are generally carried out at a temperature somewhat above the melting point of the starting compounds. This is a convenient method for preparing benzimidazoles when monoacyl derivatives are easily obtainable. The procedure may be improved by heating the monoacyl derivative of diamine in an atmosphere of nitrogen to prevent oxidation (Kelly, 1945).
