The ammonolysis of esters in liquid ammonia [PDF]
, 2013 The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Reactions radicalaires dans des milieux protiques et aprotiques : comparaisons entre les cyclisations reductives electrochimiques catalysees par des complexes du nickel [PDF]
, 2009 The electrochemical reductive cyclisation of unsaturated organic halides in the presence of Ni(II) complexes as catalysts was examined in aprotic solvents such as DMF and in protic solvents such as ethanol, butanol or ethanolewater mixtures.

Thermal reversion of spirooxazine in ionic liquids containing the [NTf2]- anion [PDF]
, 2009 We have compared the rate of thermal reversion of Spirooxazine (SO) from its merocyanine (MC) form within ionic liquids and molecular solvents. Et(30) and Kamlet-Taft parameter studies indicate ILs are comparable to polar protic and aprotic solvents. The

Theoretical Investigation of Solvation Effects on the Tautomerism of Maleic Hydrazide
E-Journal of Chemistry, 2012 A DFT study is used to calculate structural data of tautomers of maleic hydrazide (MH) in the gas phase and selected solvents such as benzene (non-polar solvent), tetrahydrofuran (polar aprotic solvent) and methanol (protic solvent), dimethyl sulfoxide ...

Synthesis method of asymmetric gold particles. [PDF]
, 2017 Asymmetric particles can exhibit unique properties. However, reported synthesis methods for asymmetric particles hinder their application because these methods have a limited scale and lack the ability to afford particles of varied shapes.
