Toward a Hexagonal Grid Polymer: Synthesis, Coupling, and Chemically Reversible Surface-Pinning of the Star Connectors, 1,3,5-C_6H_3(CB_10H_10CX)_3

摘要

A synthetic approach to a two-dimensional grid polymer is proposed and the execution of initial steps is describel. Pd-catalyzed coupling of (1, 12-dicarba-closo-dodecaboran-1-yl)copper (10) with iodobenzene, m- diiodobenzene, and 1,3,5-triiodobenzene yielded the known 1, 12-dicarba-closo-dodecaboran-1-ylbenzene (3) and the new m-bis (1,12-dicarba-closo-dodecaboran-1-yl)benzene (4) and 1,3,5-tris(1,12-dicarba-closo-dodecaboran-1-yl)benzene (1), respectively.
