Synthetic Route of 214894-89-0, Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic. In a document type is Article, and a compound is mentioned, 214894-89-0, Name is 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine, introducing its new discovery.
Two simple TADDOL-derived monodentate ligands, the (1R,2S)-2- phenylcyclohexanol-derived phosphite and the N,N-(phenylbenzyl)-phosphoramidite, give comparably high levels of enantioselectivity (90-96% ee) in the rhodium-catalyzed hydroborations of substituted styrenes bearing either electron-donating or electron-withdrawing substituents. Rhodium(I) chloride and tetrafluoroborate catalyst precursors give comparable results. Pinacolborane is superior to catecholborane in these reactions.
