Geminal and Vicinal 13C-13C Coupling Constants in Carboxylic Acid Derivatives
Chaloner, Penny A.
, p. 1028 - 1032 (2007/10/02)
Geminal 13C-13C coupling constants in αβ-unsaturated azlactones and the acids and esters derived from their hydrolysis are large and strongly dependent of configuration.Coupling constants in simple 13C1-labelled carboxylic acids are also reported; vicinal couplings show a strong geometric dependence but the geminal couplings depend mainly on hybridisation.
The Mechanism of Asymmetric Homogeneous Hydrogenation. Rhodium(I) Complexes of Dehydroamino Acids Containing Asymmetric Ligands Related to Bis(1,2-diphenylphosphino)ethane
Brown, John M.,Chaloner, Penny A.
, p. 3040 - 3048 (2007/10/02)
The course of hydrogenation of dehydroamino acids by cationic rhodium complexes derived from bis(1,2-diphenylphosphino)ethane has been studied by phosphorus and carbon NMR.The parent complex reacts with hydrogen (1 atm) in methanol to form norbornane and
