Title
Synthesis and Solution Chemistry of Metal Hydrides from Cationic Rhodium(Ⅰ) Catalyst Precursors [(L-L)Rh(NBD)]ClO4 (L-L = Fe(η5-C5H4PBut2)2, Fe (η5-C5H4PPhBut)2)

Abstract
The hydrogenation catalyst precursors [(L-L)Rh(NBD)]ClO4 (L-L = Fe(η5-C5H4PBut)2, Fe(η5-C5H4PPhBut)2; NBD = norbornadiene) react with H2(1 atm, 30℃, MeOH) to yield [(L-L)HRh(μ -H)3RhH(L-L)]ClO4. These hydrido species are fluxional, and variable temperature NMR studies show the existence of a number of equilibria involving both fluxional and non-fluxional species. The synthesis, solution structures, and fluxional behaviors of these hydrides are described.
