A novel amide-assisted rearrangement reaction of hydroxybenzimidoyl chloride has been established for the efficient synthesis of 1,3-diphenylurea derivatives. A variety of electronically and sterically different 1,3-diphenylurea derivatives can be obtained in good to excellent yields, and a proposed reaction mechanism is also presented.

By employing thiamine (vitamin B1) as the catalyst, the synthesis of furoin from furfuraldeyde has been developed. Furoin is oxidized to furil by Cu(OAc)2-NH4NO3 as an oxidant. The reaction condition is optimized and the reaction mechanism is discussed in this paper. The synthesized furoin and furil are characterized by means of Mass, IR and UV spectrum.
