A theoretical model Hamiltonian [J. Chem. Phys. 2013, 138, 064308] for describing vibrational spectra associated with the CH stretch of CH2 groups is extended to molecules containing methyl and methoxy groups. Results are compared to the infrared (IR) spectroscopy of four molecules studied under supersonic expansion cooling in gas phase conditions. The molecules include 1,1-diphenylethane (DPE)...

Asymmetric Michael additions of 1,3-dicarbonyl compounds to N-substituted maleimides were carried out using primary amine-(thio)phosphoramide bifunctional chiral organocatalysts derived from optically pure C2-symmetric 1,2-diamines. The addition ethyl 2-fluoroacetoacetate the 1,2-diphenylethane-1,2-diamine thiophosphoramide catalyst afforded various succinimides substituted with fluorine bearin...

The effect of NaI on hydrogenation diphenylacetylene catalyzed by the water-soluble [{RuCl(mtppms-Na)2}2(µ-Cl)2] (1) (mtppms-Na = meta-monosulfonated triphenylphosphine sodium salt) is reported. Hydrogenations were performed under mild conditions (P(H2) 1 bar, T 50–80 ?) in aqueous–organic biphasic reaction mixtures wherein catalyst was dissolved aqueous phase various pHs. In acidic solutions, ...
