Abstract

The synthesis and structural characterization of a mixed-sandwich (η5-C5Me5) Rh (III) complex of the cyclometalated phosphine PMeXyl2 (Xyl= 2, 6-C6H3Me2) with unusual κ4-P, C, C′, C′′ coordination (compound 1-BAr f; BArf= B (3, 5-C6H3 (CF3) 2) 4) are reported. A reversible κ4 to κ2 change in the binding of the chelating phosphine in cation 1+ induced by dihydrogen and hydrosilanes triggers a highly efficient Si− H/Si− D (or Si− T) exchange ...
