摘要：

The efficient fourfold radical phosphanylation of 2,2,2′,2′- tetrabromobiphenyl with a bis(stannyl)phosphane followed by oxidation produces a highly strained biphenyl with two phosphoryl bridges (see picture). Extended π-conjugated compounds consisting of this core unit can be also synthesized by using the same approach. The two phosphoryl bridges significantly alter the electronic structure, making this biphenyl a unique electron-accepting scaffold. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
