Popodko, Usein M. DzhemilevAbstractBoronic esters (dicycloheptylalkylboronates, dicyclooctylalkylboronates, dicyclododecylalkylboronates, dibicyclo[2.2.1]hept-2-ylalkylboronates) are produced with yields ranging from moderate to excellent (52–96%) by the reaction between cyclic olefins (cycloheptene, cis-cyclooctene, cis/trans-cyclododecene, norbornene) and alkyldichloroboranes (alkyl = Et, n-Pent) in the presence of metallic magnesium and the Cp2TiCl2 catalyst with subsequent addition of water.Graphical abstract
