The article was titled 《Organozinc pivalates for cobalt-catalyzed difluoroalkylarylation of alkenes》.Application In Synthesis of Ethylbromofluoroacetate The article contains the following contents:

A cobalt-catalyzed regioselective difluoroalkylarylation of both activated and unactivated alkenes with solid arylzinc pivalates and difluoroalkyl bromides through a cascade Csp3-Csp3/Csp3-Csp2 bond formation under mild reaction conditions. Indeed, a wide range of functional groups on difluoroalkyl bromides, olefins, 1,3-dienes as well as (hetero)arylzinc pivalates are well tolerated by the cobalt-catalyst, thus furnished three-component coupling products in good yields and with high regio- and diastereoselectivity. Kinetic experiments compared arylzinc pivalates and conventional arylzinc halides highlighted the unique reactivity of these organozinc pivalates. Mechanistic studies strongly supported that the reaction involved direct halogen atom abstraction via single electron transfer to difluoroalkyl bromides from the in-situ formed cobalt(I) species, thus realized a Co(I)/Co(II)/Co(III) catalytic cycle.

Riente, Paola; Fianchini, Mauro; Llanes, Patricia; Pericas, Miquel A.; Noel, Timothy published their research in Nature Communications on December 31 ,2021. The article was titled 《Shedding light on the nature of the catalytically active species in photocatalytic reactions using Bi2O3 semiconductor》.HPLC of Formula: 401-55-8 The article contains the following contents:

The importance of discovering the true catalytically active species involved in photocatalytic systems allows for a better and more general understanding of photocatalytic processes, which eventually may help to improve their efficiency. Bi2O3 has been used as a heterogeneous photocatalyst and is able to catalyze several synthetically important visible-light-driven organic transformations. However, insight into the operative catalyst involved in the photocatalytic process is hitherto missing. Herein, we show through a combination of theor. and exptl. studies that the perceived heterogeneous photocatalysis with Bi2O3 in the presence of alkyl bromides involves a homogeneous BinBrm species, which is the true photocatalyst operative in the reaction. Hence, Bi2O3 can be regarded as a precatalyst which is slowly converted in an active homogeneous photocatalyst. This work can also be of importance to mechanistic studies involving other semiconductor-based photocatalytic processes. In addition to this study using Ethylbromofluoroacetate, there are many other studies that have used Ethylbromofluoroacetate(cas: 401-55-8HPLC of Formula: 401-55-8) was used in this study.
