Zhang, Xiao published the artcileSilver(I)-catalyzed carboxylation of arylboronic esters with CO2, Recommanded Product: 4-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzonitrile, the publication is Chemical Communications (Cambridge, United Kingdom) (2012), 48(50), 6292-6294, database is CAplus and MEDLINE.
A variety of arylboronic esters were efficiently carboxylated with CO2 using a simple AgOAc/PPh3 catalyst, affording the corresponding carboxylic acids in good yield. This simple and efficient silver(i) catalytic system showed wide functional group compatibility.
