New discoveries in chemical research and development in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Gomaa, MAM, once mentioned the application of 3317-61-1, Name is 5,5-Dimethyl-1-pyrroline N-oxide, molecular formula is C6H11NO, molecular weight is 113.1576, MDL number is MFCD00005279, category is pyrrolines. Now introduce a scientific discovery about this category, Application In Synthesis of 5,5-Dimethyl-1-pyrroline N-oxide.
Reaction of diimines and azines with diphenylcyclopropenone
1-Cyclohexyl-2-cyclohexylaminomethylene-4,5-diphenyl-1,2-dihydropyrrol-3-one 4a and 1-aryl-2-arylamino-methylene-4,5-diphenyl-1,2-dihydropyrrol-3-ones 4b, c as the E-form are synthesized by the reaction between N,N’-dicyclohexylethane-1,2-diylidenediamine 2a and N,N’-diarylethane-1,2-diylidenediamines 2b, c with diphenylcyclopropenone 1 through a formal [2 + 3] cycloaddition reaction. The structure assignment of 4a is confirmed on the basis of an X-ray crystal-structure determination. Similarly, diaryl azines 8a-c react with 1 through a formal [2 + 3] cycloaddition reaction to give the non-isolable product Delta(4)-pyrrolin-3-ones 10a-c which undergo oxidative rearrangement to afford ultimately the indenone derivatives 9a-c.
