ABSTRACT:
Phosphines of the formula (I) and the preparation of these phosphines ##STR1## where Ar--Ar is a biphenyl radical, a 1-phenylnaphthyl radical or a 1,1'-binaphthyl radical, the CH.sub.2 group and the CH.sub.3 radical are each in the ortho position to the Ar--Ar bond, R is F, an alkyl radical or alkoxy radical each having from 1 to 8 carbon atoms, n is an integer from 0 to 4, R.sup.1 and R.sup.2 independently of one another, are an alkyl radical having from 1 to 10 carbon atoms, a cycloaliphatic radical having from 5 to 10 carbon atoms, or a radical Ar.sup.1 -(R.sup.3).sub.m, where Ar.sup.1 is a phenyl or naphthyl radical, R.sup.3 is F, Cl, CF.sub.3, SO.sub.3 H, SO.sub.3 Me (Me=Li, Na or K), a dialkylamino radical having from 2 to 8 carbon atoms, an alkyl radical or alkoxy radical each having from 1 to 8 carbon atoms and m is an integer from 0 to 5, or R.sup.1 and R.sup.2 together with the phosphorus atom form a 4-membered to 8-membered ring to which can be fused.
