Abstract

The hydroboration of three families of functionalized olefins (1-bromo-and 1, 3- dibromopropenes, allylamines, 2, 3-dihydrofuran) by pinacolborane and catecholborane has been studied under various experimental conditions. For 1-bromo-and 1, 3- dibromopropenes, pinacolborane (PBH) is a poor reagent that requires the use of high pressure in ethereal solvents and provides only by-products, resulting from the undesired ...
