Optically active 1,1′-di-tert-butyl-2,2′-dibenzophosphetenyl: a highly strained P-stereogenic diphosphine ligand

Add time:09/04/2019    Source:sciencedirect.com

Both enantiomers of 1,1′-di-tert-butyl-2,2′-dibenzophosphetenyl were prepared from 2-bromobenzyl chloride and tert-butyldichlorophosphine. These ligands exhibited excellent enantioselectivity in the rhodium catalyzed asymmetric hydrogenation of methyl α-acetylamidocinnamate.
