英文摘要: Nitrobenzene and its derivatives can react with 2-aminopyridine as coreagent by using the method of selenium-catalyzed CO reductive carbonylation. Partial products were identified by IR, H-1 MAR, C-13 NMR, HPLC and element analysis. The obtained products are not three kinds of ureas that are almost equal in amount, but are mainly unsymmetrical pyridylureas. The reductive carbonylation of nitro compounds with primary amines as coreagents has been developed by using the catalytic system of Se/CO. This synthetic method can be expected to synthesize a series of phenyl pyridylureas containing substituting group on the benzene ring. It is indicated that the synthetic method is simple and also very easy to operate. At present, the method to synthesize these compounds has not been found in the literature.
