Chemical Research Letters, April 2021. With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation we’ve spent the past two centuries establishing. 22884-95-3, Name is 3,4-Dimethylbenzonitrile, molecular formula is C9H9N, Application In Synthesis of 3,4-Dimethylbenzonitrile, belongs to isothiazole compound, is a common compound. In a patnet, author is Mihara, Gen, once mentioned the new application about 22884-95-3.
A Rh(III)-catalyzed annulative coupling of 3,5-diarylisothiazoles and alkynes is reported. The N-S bond in the isothiazole ring acts as an internal oxidant to regenerate the Rh(III) species in combination with an external Cu(II) oxidant, and the corresponding 1:2 coupling products are obtained. The remarkable difference in the reaction outcome between isothiazoles and the relevant isoxazoles has been investigated by DFT calculations, revealing that the relative stability of the enolate intermediates dictates the product selectivity.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 22884-95-3. Application In Synthesis of 3,4-Dimethylbenzonitrile.
