N-heterocyclic Compounds. A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring s. After the synthesis of stable pentacoordinated tetrachlorosilane coordinated by an nhc.

N heterocyclic compounds are important chemicals and their reductive synthesis using h2 under mild conditions is attractive but challenging. Under optimal conditions 2 methyl pyrazine mp and 4 5 methyl imidazole mi were produced within 15 min with combined yields of around 40.

New n heterocyclic compounds. However carbohydrates as common minor constituents of technical lignins have been demonstrated to be a potential source of n heterocyclic ecotoxic compounds ethyl acetate extracts of ammoxidation mixtures of the monosaccharides glucose and xylose exhibited considerable growth. A one step reaction system has been developed to convert glucose and other renewable carbohydrates into important n heterocyclic compounds in ammonia solution. After the synthesis of stable pentacoordinated tetrachlorosilane coordinated by an nhc.
