TetraMe-BITIANP

Another class of chiral diphosphine ligands bearing two interconnected thiophene rings, has been successfully developed by Sannicolo et al. These bis(diphenylphosphino)[Z)]thiophene ligands, called tetraMe-BITIANP and... [Pg.248]

CH2CI2 occurs 9.8-fold faster than that of the S isomer, and the equilibration between the enantiomeric substrates is 4.4-fold faster than hydrogenation of the slow-reacting S substrate. On the other hand, hydrogenation of racemic 3-acetyltetrahy-drofuran-2-one catalyzed by the cationic (l )-BINAP-RuCl()7 -C6H6) complex gives the 3S,ri syn) alcohol in up to 97% e.e. (Eq. 2.22) [120, 158bj. A similar result is obtained by use of a tetraMe-BITIANP-Ru complex [49]. [Pg.24]

Furthermore, axially chiral bidentate ligand of substantially different structure possessing five-membered heteroaromatic rings (bis-tiophene moiety), tetraMe-BITIANP (46) in optically pure form has been S3mthesized as well are and used primarily for the enantioselective hydrogenation of functionalized ketones. [Pg.682]
