Reversible C−H activation, facile C−B/B−H metathesis and apparent hydroboration catalysis by a dimethylxanthene‐based frustrated Lewis pair

Abstract:

A dimethylxanthene‐based phosphine/borane frustrated Lewis pair (FLP) is shown to effect reversible C−H activation, cleaving phenylacetylene, PhCCH, to give an equilibrium mixture of the free FLP and phosphonium acetylide in CD2Cl2 solution at room temperature. This system also reacts with B−H bonds although in a different fashion: reactions with HBpin and HBcat proceed via C−B/B−H metathesis, leading to replacement of the ‐B(C6F5)2 Le...
