《Cobalt(I)-Catalyzed Borylation of Unactivated Alkyl Bromides and Chlorides》 was published in Organic Letters in 2020. These research results belong to Verma, Piyush Kumar; Prasad, K. Sujit; Varghese, Dominic; Geetharani, K.. Synthetic Route of C4H7Br The article mentions the following:
A Co-complex-catalyzed borylation of a wide range of alkyl halides with a diboron reagent (B2pin2 or B2neop2) was developed under mild reaction conditions, demonstrating the 1st Co-mediated cross-coupling with alkyl electrophiles. This protocol allows alkyl boronic esters to be accessed from alkyl halides, including alkyl chlorides, which were used rarely as coupling partners. Mechanistic studies reveal the possible involvement of an alkyl radical intermediate in this Co-mediated catalytic cycle. After reading the article, we found that the author used (Bromomethyl)cyclopropane(cas: 7051-34-5Synthetic Route of C4H7Br)
(Bromomethyl)cyclopropane(cas: 7051-34-5) is used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.Synthetic Route of C4H7Br
