Abstract

1-Iodo-2,6-bis(4-methoxy-phenyl)benzene (BipapI) was prepared in a Grignard reaction from 4-bromo-anisol and 2,6-dibromo-1-iodo-benzene in tetrahydrofuran (61% yield). Treatment of BipapI with n-butyllithium in hexane/diethylether gave the corresponding terphenyl-lithium compound BipapLi which crystallized as the dietherate in 83% yield. The structure of BipapLi · (OEt2)2 has been determined by single crystal X-ray methods. The molecule is a monomer in the lattice, and the lithium atom is three-coordinate. Preparation of BipapLi in the presence of PbCl2 in diethylether gave a green solution, from which yellow crystalline (n -Bu)(Bipap)2PbI was isolated in 73% yield. In the crystal this triorganolead(IV) iodide is monomeric and has tetrahedrally four-coordinate lead atoms.
