	abstract = {Interaction of cis, trans, cis-[Rh(H)(2)(PR3)(2)(acetone)(2)] PF6 complexes (R = aryl or R-3 = Ph2Me, Ph2Et) under H-2 with E-semicarbazones gives the Rh(III)-dihydrido-bis(phosphine)-semicarbazone species cis, trans-[Rh(H)(2)(PR3)(2)-{R{\textquoteright}(R")C=N-N(H)CONH2}]PF6, where R{\textquoteright} and R" are Ph, Et, or Me. The complexes are generally characterized by elemental analysis, P-31{H-1} NMR, H-1 NMR, and IR spectroscopies, and MS. X-ray analysis of three PPh3 complexes reveals chelation of E-semicarbazones by the imine-N atom and the carbonyl-O atom. In contrast, the corresponding reaction of [Rh(H)(2)(PPhMe2)(2)(acetone)(2)]PF6 with acelophenone semicarbazone gives the orthometalated-semicarbazone species cis-[RhH(PPhMe2)(2){o-C6H4(Me)C=N-N(H)CONH2}]PF6. The X-ray structure of E-propophenone semicarbazone is also reported. Rhodium-catalyzed, homogeneous hydrogenation of semicarbazones was not observed even at 40 atm H-2.},

	abstract = {Interaction of the cis-[Rh(PR3)(2)(Solv)(2)]PF6 complexes (R = Ar or R-3 = Ph2Me, Solv solvent) under Ar with semicarbazones bearing a phenyl group on the imine-C atom gives the rhodium(III)-hydrido-bis(phosphine)-orthometallated semicarbazone species [RhH(PR3)(2){(o-C6H4(R{\textquoteright})C=N-N(H)CONH2}]PF6 (R{\textquoteright} = Me or Et), which are characterized generally by elemental analysis, P-31{H-1} and H-1 NMR spectroscopy, and mass-spectrometry. The PPh3-containing complex with R{\textquoteright} = Me, structurally characterized by X-ray analysis, reveals coordination of the semicarbazone by the ortho-C atom, the imine-N atom, and the amide-carbonyl group. For a semicarbazone containing no Ph group, the rhodium(I) complex [Rh(PR3)(2)(Et(Me)C=N-N(H)CONH2)]PF6, containing the eta(2)-semicarbazone bonded via the imine-N and carbonyl, is formed. Attempts to hydrogenate the C=N moiety in the complexes or to catalytically hydrogenate the semicarbazones were unsuccessful.},
