On February 21, 2020, Nanda, Tanmayee; Ravikumar, P. C. published an article.Quality Control of 1,3-Diphenylurea The title of the article was A Palladium-Catalyzed Cascade C-C Activation of Cyclopropenone and Carbonylative Amination: Easy Access to Highly Functionalized Maleimide Derivatives. And the article contained the following:
We describe herein the first report on palladium-catalyzed C-C bond activation of cyclopropenone and concomitant carbonylative amination to produce maleimides. The interesting aspect of this reaction is that the sacrificial elimination of carbon monoxide from the substrate is efficiently recaptured by one of the intermediates in the catalytic cycle for the formation of maleimides. 18O isotopic studies confirmed that the source of carbon monoxide is from cyclopropenone. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Quality Control of 1,3-Diphenylurea
