In 2019,Angewandte Chemie, International Edition included an article by Friese, Florian W.; Studer, Armido. Synthetic Route of C3H3ClO3. The article was titled 《Deoxygenative Borylation of Secondary and Tertiary Alcohols》. The information in the text is summarized as follows:
Two different approaches for the deoxygenative radical borylation of secondary and tertiary alcs. are presented. These transformations either proceed through a metal-free silyl-radical-mediated pathway or utilize visible-light photoredox catalysis. Readily available xanthates or Me oxalates are used as radical precursors. The reactions show broad substrate scope and high functional-group tolerance, and are conducted under mild and practical conditions. In the part of experimental materials, we found many familiar compounds, such as Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Synthetic Route of C3H3ClO3)
Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Synthetic Route of C3H3ClO3
