title: The drastic effect of cobalt and chromium catalysts in the borylation of arylzinc reagents.
abstract: A new synthetic approach to arylboronic esters from arylzinc reagents with boryl electrophiles MeOB(OR)2 has been developed. Furthermore, this protocol could be applied to the cyclization/borylation of alkynylaryl iodides to afford cyclized vinylboronic esters.
