제목 Ligand-Controlled Direct Hydroformylation of Trisubstituted Olefins
초록 Hydroformylation is a highly atom-economical synthetic reaction to prepare aldehydes by addition of CO and H2 to olefins. It is an industrially utilizing homogeneous catalytic reaction as the resulting aldehyde products are used to further produce oxo-alcohols more than 10 million tons annually. Although Co-based catalysts were initially developed, Rh-based catalysts have been the topic of recent research because the regioselectivity and stereoselectivity of Rh-catalyzed hydroformylation can be efficiently controlled by ligands. Many efficient ligands for hydroformylation have been developed, but it has been a challenge to achieve direct hydroformylation of tri-substituted olefins. We recently reported a new class of π–accetor ligand, bicyclic bridgehead phosphoramidite (briphos). Here we introduce our birphos ligand and present the Rh-catalyzed direct hydroformylation of tri-substituted olefins by ligand modification of briphos ligands
