The essential oil (EO) obtained from the roots of Valeriana rigida Ruiz & Pav. (Caprifoliaceae), collected in moorland region Chimborazo Province, Ecuador, was analyzed for first time. chemical profile qualitatively and quantitatively using GC-MS GC-FID, respectively. With both detectors, two stationary phases different polarities were used. A total 56 compounds identified, most abundant components (>3% on at least one column) a mixture cyclosativene α-ylangene (4.5-4.4%), α-copaene...
Acyl(σ-norbornenyl)rhodium(III) dimer [Rh(μ-Cl)(C9H6NCO)(C7H9)L]2 (1) (C7H9 = σ-norbornenyl; L 4-picoline, isoquinoline) reacts with diphenylphosphine oxide (SPO) to undergo a one-pot reaction involving (i) cleavage of the chloride bridges and coordination phosphine, (ii) C-C bond coupling between acyl norbornenyl in 18e species, (iii) ligand-assisted outer-sphere O(P)-to-O(C) hydrogen transfer, afford mononuclear 16e species [RhCl{(C9H6NC(O)C7H9)(Ph2PO)H}(L)] (2) containing...
Abstract [Rh(nbd)Cl] 2 (nbd=norbornadiene) reacts with quinoline‐8‐carbaldehyde (C 9 H 6 NCHO) and pyrazole (Hpz) affording, depending on Rh/Hpz ratio, acyl‐alkyl [Rh(μ‐Cl)(C NCO)(Hpz)(σ‐C 7 )] ( 1 ) or [RhCl(C NCO)(Hpz) (σ‐norbornenyl)] ), stereoselectively as confirmed by DFT calculations. Hydrogen bond between NH‐pyrazole O‐acyl occurs. react diphenylphosphine oxide (SPO) giving 16e NC(nbyl))(Ph PO)(Hpz)] 3 through SPO κ ‐P‐coordination, C−C coupling acyl norbornenyl outer‐sphere...
DFT-B3LYP calculations have been carried out to assess the fate of Pd/X group intermolecular exchange in [PdBr(PH 3 )(C 6 H 5 X)] system, where X is either H, an electropositive atom, or a such as Li, Na, BH 2 , AlH BeH BeCH and electronegative F, Cl, Br, CH OH, SH. The transfer best viewed involving migration proton between two phenyls. At variance with this result, more entities = BeH, not complete. It stops halfway yield stable structure which can experience interactions phenyl groups...
Conformational mobility is a core property of organic compounds, and conformational analysis has become pervasive tool for synthetic design. In this work, we present experimental computational (employing Density Functional Theory) evidence unusual intramolecular hydrogen bonding interactions in series α-acylmethane derivatives, as well discussion the consequences thereof their NMR spectroscopic properties.
