WebOrganocatalisi. In chimica organica, con il termine organocatalisi si intende la catalisi di reazioni dove il catalizzatore usato per accelerare la reazione è una piccola molecola organica, priva di elementi inorganici come i metalli e contenente carbonio, idrogeno, zolfo. Il termine fu coniato nel 1935 dal chimico tedesco Wolfgang Langenbeck. how to see fers accountWeb6 mar 2024 · Once again the Singleton group reports experiments and computations that require serious reconsideration of our notions of reaction mechanisms. 1 In this paper they examine the reaction of dichloroketene with labeled cis -2-butene.
