Synthesis of functionalized triphenylenes by selective ether cleavage with B-bromocatecholborane

[摘要]：This paper presents an efficient synthetic procedure for the preparation of mono-, di- and trifunctionalized triphenylene derivatives starting from the readily available hexakis(pentyl oxy)triphenylene by selective ether cleavages with B-bromocate-cholborane (2-bromo-1,3,2-benzodioxaboroles). Functionalized triphenylene derivatives are the precursor molecules for the preparation of processible triphenylene discotic dimers, oligomers, polymers and networks.
