Solvent-free Synthesis of 1,3-Diarylureas by Selenium-catalyzed Reductive Carbonylation of Nitroarenes

摘要

@@ Introduction The development of cleaner technologies is a major emphasis in green chemistry. Among the several aspects of green chemistry, solvents are high on the list of damaging chemicals for two simple reasons: (1) they are used in huge amounts and (2) they are usually volatile liquids. Reducing/replacing damaging organic solvents from the reaction medium is of utmost importance presently.
