Rhodium(II) complexes with dioximes [Rh(Hdmg)2(PPh3)]2 [I] (Hdmg=monoanion of dimethylglyoxime) and [Rh(Hdmg)(ClZndmg)(PPh3)]2 [II] catalyse hydroformylation and hydrogenation reactions of 1-hexene at 1 MPa CO/H2 and 0.5 MPa H2 at 353 K, respectively. Hydroformylation with complex [I] produces 94% of aldehydes (n/iso=2.2) and 6% 2-hexene whereas the second catalyst [II] gives ca. 40% of aldehydes (n/iso=2.1) and 60% of 2-hexene. Corresponding Rh(III) complexes are inactive in hydroformylation except of RhH(Hdmg)2(PPh3) [III], which shows activity similar to [I]. Complexes [Rh(Hdmg)2(PPh3)]2 [I], [Rh(Hdmg)(ClZndmg)(PPh3)]2 [II], RhH(Hdmg)2(PPh3) [III] and [Rh(Hdmg)2(PPh3)2]ClO4 [V] catalyse 1-hexene hydrogenation with an average TON ca. 18 cycles/mol [Rh]×min. Complex [II] has also been found to catalyse hydrogenation of cyclohexene, 1,3-cyclohexadiene and styrene.
