<p>Novel trans-1,2-bis(dihalophosphino) cycloalkanes (I) wherein the alkane moiety contains from 3 to 12 carbon atoms, trans-1,2-bis ADdi(X)-phosphino BDcycloalkanes (II) wherein the alkane moiety contains from 3 to 12 carbon atoms and X is either hydrocarbyl or alkoxy and the resolved enantiomers of (II). Compounds (I) are produced by reacting a C3 to C12 cyclic olefin with a trivalent phosphorus compound of the formula PX3 wherein X is chlorine or bromine in the presence of elemental phosphorus. Compounds (I) are converted to compounds (II) by reaction with an (X)-containing carbon nucleophile. </p> |
