Asymmetric hydrogenation of isobutyrophenone using a [(Diphosphine) RuCl2 (1,4-diamine)] catalyst.
[reaction: see text] The use of three chiral 1,4-diamines in the [(diphosphine) RuCl(2) (diamine)] catalyst system is demonstrated in the hydrogenation of acetophenone. The use of a 1,4-diamine… Expand
