✦ Synopsis

The reactions of four equivalents of heterocyclic aryllithium compounds with phosphorus trichloride or phosphorus oxychloride gave symmetrical heterocyclic biaiyls in good yields. A similar coupling was found in the reactions of three equivalents of the lithi u m compounds with thionyl chloride.
