Reaction of alkane-1,n-diylbisdiphenylphosphines with lithium in tetrahydrofuran gives only the diphosphides resulting from cleavage of a phosphorusaryl bond at each end of the chain; the course of the reaction is independent of chain length. The X-ray structure of the ethane diphosphide is presented and a possible mechanism discussed.
