Abstract:
1. A compound of the formula I having at least two chiral centres 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 Q is a bivalent ferrocenyl radical without a planar chiral centre, to which the phosphorus atom of the secondary phosphine is bonded directly or via a C the —P*(═O)HR P* is a chiral phosphorus atom, and R where R
