Pyridinolysis of Diethyl Phosphinic Chloride in Acetonitrile

Kinetics and Mechanism of Pyridinolysis of Aryl Dithiocyclopentanecarboxylates in Acetonitrile

Kinetic studies on the pyridinolysis of aryl dithiocyclopentanecarboxyaltes 2 were carried out at 60.0 C in acetonitrile. In the aminolysis of 2, the βX values were 0.5 0.8 with anilines, and there was no breakpoint. However, in the pyridinolysis of 2, biphasic Brönsted plots were obtained, with a change in slope from a large value (βX ≅ 0.7) to a small value (βX ≅ 0.4) at pKa = 5.2. This was a...

Effect of Sodium Ions on the Electrochemical Reduction of Diethyl Fumarate in Dimethylsulfoxide and Acetonitrile

4-Chloro­selanyl-3,5-diethyl-1H-pyrazol-2-ium chloride

In the cation of the title compound, C(7)H(12)ClN(2)Se(+)·Cl(-), the ethyl-ene groups and the Se-Cl fragment adopt a cis configuration with a C-Se-Cl angle of 96.09 (6)°. In the crystal, inter-molecular N-H⋯Cl hydrogen bonds link two cations and two chlorine anions into centrosymmetric clusters. π-π inter-actions between the pyrazole rings [centroid-centroid distance of 3.530 (2) Å] link these ...

Effect of added Dimethyl sulphoxide on the Solvolysis of Cinnamoyl Chloride in Aqueous Acetone and Acetonitrile

Kinetic studies on solvolysis of cinnamoyl chloride in aqueous acetone and acetonitrile with lesser water content shows an order 2.6 with respect to water and it is comparable to that of benzoyl chloride. The relatively greater enthalpy and lesser negative entropy of activation compared to benzoyl chloride favours an SN2 mechanism for cinnamoyl chloride rather than addition elimination mechanis...

Meth­yl(phen­yl)phosphinic acid

The crystal structure of the title compound, C(7)H(9)O(2)P, displays O-H⋯O hydrogen bonding , which links individual mol-ecules related via the c-glide plane and translational symmetry along the crystallographic b-axis direction into continuous chains.
