Electric Literature of 13395-16-9, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. In an article, authors is Saha, Bijali, once mentioned the application of Electric Literature of 13395-16-9, Name is Bis(acetylacetone)copper,molecular formula is C10H16CuO4, is a conventional compound.
Vinylogous Wolff Rearrangement of Cyclic beta,gamma-Unsaturated Diazomethyl Ketones: a New Synthetic Method for Angularly Functionalised Polycyclic Systems
Decomposition of the rigid polycyclic beta,gamma-unsaturated diazomethyl ketones (1a) and (1b) and (2a) and (2b) promoted by ‘activated CuO’, Cu(acac)2, Cu(OTf)2, or Ni(acac)2 in the presence of methanol are shown to give mainly the corresponding rearranged gamma,delta-unsaturated angularly substituted esters (3a) and (3b) and (8a) and (8b) together with the alpha-methoxy ketones (4a) and (4b) and (9a) and (9b).While photo-Wolff rearrangement of the diazo ketones leads to the corresponding homologous esters (5a) and (5b) and (10a) and (10b) the silver benzoate-triethylamine induced reaction gives the rearranged esters in addition to the homologous esters.
