Abstract

Abstract : An intramolecular P/Al-based FLP with a biphenylene scaffold is synthesized by a convenient Al-Sn exchange. Despite the spacer the FLP functions interact leading to a strained compound, capable of CO2 binding and unprecedented allene activation. Abstract : FLPs featuring aluminum–phosphane interactions, spring-loaded by a rigid biphenylene linker, have been accessed through a route where trimethyltin units at phosphane-functionalized organic backbones are exchanged by an AlCl2 moiety. Upon contact with substrates like CO2 these are readily bound by the Al/P site with release of strain. The system could also be utilized for a unique reactivity, namely the activation of allene.
