Reference of 90766-97-5, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 90766-97-5, 5-Bromo-6-phenylpyridazin-3(2H)-one, introducing its new discovery.
Several 6-phenyl-3(2H)-pyridazinones bearing different alkynyl groups at position 5 have been prepared by a palladium-catalysed Sonogashira cross-coupling reaction. An interesting base-promoted electronically permitted isomerization has been observed during the coupling of 1-phenyl-2-propyn-1-ol. This rearrangement afforded the E-chalcone 6 in excellent yield.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 90766-97-5. In my other articles, you can also check out more blogs about 90766-97-5
