Copper-Catalyzed Reagent-Controlled Regioselective Cyanoborylation of Vinylarenes

A copper-catalyzed borylation/benzylic cyanation of vinylarenes whose regioselectivity is seemly common but scarcely achieved is reported. This unprecedented regioselectivity is realized through a structure-distinctive cyanating reagent, dimethylmalononitrile. This reaction can be applied to both ?-extended and simple vinylarenes with various diboron reagents, and it exhibits good functional group compatibility. With the ample transformations of cyano and boronate groups, this reaction provides expedient access to complex organic structures.

Route to Air and Moisture Stable beta-Difluoroboryl Acrylamides

A method for the preparation of air stable difluoroboryl acrylamides is reported. In contrast to the ubiquitous organotrifluoroborate salts, difluoroboryl acrylamides are relatively nonpolar and are readily purified by silica chromatography. Difluoroboryl acrylamides serve as efficient substrates in cross-coupling reactions to afford the corresponding trisubstituted acrylamides in good to excellent yields. The utility of the difluoroboryl group in various chemical transformations is presented.

Step-Edge Assisted Direct Linear Alkane Coupling

Direct coupling of alkanes via C?H activation of terminal methyl groups has acquired tremendous interests both scientifically and technically. Herein we present the results of linear alkane-coupling at the step edges of Cu surfaces at modulated temperatures. Combining the observations of scanning tunneling microscopy (STM) with density functional theory plus dispersion (DFT-D) calculations, we elucidate the mechanism of the reaction and demonstrate that the low activation barrier relies on heterogeneous catalysis at the upper step edges, where low-coordinated surface atoms are present. We further reveal the generality of the reaction, so that it can be applied on the step edges of different facets of surfaces.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 4923-87-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4923-87-9, in my other articles.

Synthesis of aryl and arylmethyl phosphonates by cross-coupling of aryl or arylmethyl halides (X = I, Br and Cl) with diisopropyl H-phosphonate

An efficient and generally applicable protocol for the palladacycle- catalysed arylation or K2CO3-promoted arylmethylation of diisopropyl H-phosphonate has been developed. The remarkable features of the palladacycle-catalysed arylation reaction include wide substrate scope (aryl iodides, bromides and chlorides), significant shortening of the reaction time (2 or 3 h) and a low catalyst loading of 1 mol-%. Note that with the base K 2CO3 as promoter, arylmethylation could be achieved without any palladium catalyst. Moreover, the first example of a palladium-catalysed phosphonation of inactive electron-rich aryl chlorides with tBuOK as the base has been realized. This result could be considered an important improvement and complement to earlier work of Montchamp and Han, whose catalytic systems are typically compatible with electron-deficient and electron-neutral aryl chlorides.

Scalable, Metal- and Additive-Free, Photoinduced Borylation of Haloarenes and Quaternary Arylammonium Salts

We report herein a simple, metal- and additive-free, photoinduced borylation of haloarenes, including electron-rich fluoroarenes, as well as arylammonium salts directly to boronic acids. This borylation method has a broad scope and functional group tolerance. We show that it can be further extended to boronic esters and carried out on gram scale as well as under flow conditions.
