Qiu, Hui et al. published their research in Journal of Molecular Structure in 2022 | CAS: 4298-52-6

2-Ethynylthiophene (cas: 4298-52-6) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.COA of Formula: C6H4S

Chemoselective electrocatalytic hydroboration of alkynes with pinacolborane was written by Qiu, Hui;Lv, Kang;Qu, Haoqi;Zhang, Xuguang;Yuan, Taoyue;Yao, Weiwei;Xue, Fei;Ma, Mengtao. And the article was included in Journal of Molecular Structure in 2022.COA of Formula: C6H4S This article mentions the following:

A green and sustainable non-catalytic electrochem. hydroboration of various alkynes ArCCH with HBpin has been reported for the first time, giving arylvinylboronates (E)-ArCH:CHBpin. Under catalyst-free and additive-free mild reaction conditions the corresponding alkenyl boronic esters were obtained in good to excellent yields within 30 min at room temperature A plausible reaction mechanism was proposed based on the corresponding experiments In the experiment, the researchers used many compounds, for example, 2-Ethynylthiophene (cas: 4298-52-6COA of Formula: C6H4S).
