(C5Me5)2UCl·tetrahydrofuran. Oxidative-addition and related reactions

Abstract
The first examples of organoactinide oxidative-addition of alkyl halides are reported, reactions which proceed at unprecedented rates; the results presented include the stoicheiometries of these reactions, the new complexes (C5Me5)2UX2, (C5Me5)2UX(Y), and (C5Me5)2- UY(R)(X,Y = Br, I), the series of halide exchange equilibria by which these new complexes are formed, determination of the appropriate equilibrium constants to ± 10% independent syntheses for these new complexes, and evidence for a previously unknown type of UIII to UIV redox-halide exchange equilibrium and its equilibrium constant.
