In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1293-65-8, name is 1,1′-Dibromoferrocene, introducing its new discovery. HPLC of Formula: C10Br2Fe
CHIRAL LIGANDS USED IN TRANSITION METAL CATALYSTS FOR ASYMMETRIC ADDITION REACTIONS ESPECIALLY HYDROGENATION
Ligands of the formula (I) secondary phosphine-Q-P(=O)HR1 (I) in the form of mixtures of diastereomers or pure diastereomers, in which secondary phosphine is a secondary phosphine group with hydrocarbon radicals or heterohydrocarbon radicals as substituents; Q is a bivalent bisaryl or bisheteroaryl radical with an axial chiral centre to which the two phosphorus atoms are bonded in the ortho positions to the bisaryl or bisheteroaryl bridge bond, or Q is a bivalent ferrocenyl radical with a planar chiral centre or without a planar chiral centre, to which the phosphorus atom of the secondary phosphine is bonded directly or via a C1-C4-carbon chain to a cyclopentadienyl ring, the -P*(=O)HR1 group is bonded either on the same cyclopentadienyl ring in ortho position to the bonded secondary phosphine or on the other cyclopentadienyl ring; P* is a chiral phosphorus atom, and R1 is a hydrocarbon radical, a heterohydrocarbon radical or a ferrocenyl radical, where R1 is a ferrocenyl radical with a planar chiral centre when Q is a ferrocenyl radical without a planar chiral centre. Metal complexes of these ligands are homogeneous catalysts for asymmetric addition reactions, particularly hydrogenations.
