SDS of cas: 1293-65-8, With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing.In an article, 1293-65-8, molcular formula is C10Br2Fe, belongs to iron-catalyst compound, introducing its new discovery.
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.
