A cautionary tale of basic azo photoswitching in dichloromethane finally explained
Communications ChemistryMany studies of azobenzene photoswitches are carried out in polar aprotic solvents as a first principles characterization of thermal isomerization. Among the most convenient polar aprotic solvents are chlorinated hydrocarbons, such as DCM.

Baylis−Hillman Mechanism: A New Interpretation in Aprotic Solvents
, 2016 Using reaction rate data collected in aprotic solvents, we have determined that the Baylis−Hillman rate-determining step is second order in aldehyde and first order in DABCO and acrylate.

Influence of Aprotic Solvents on the Phase Behavior of Ionic Liquid Based Aqueous Biphasic Systems
, 2016 Although aprotic solvents (ASs) have been largely explored as cosolvents of ionic liquids (ILs) for biomass resources pretreatment, the separation and recovery of ILs along with ASs were seldom investigated.

Nitrobenzene Hydrogenation to N-phenylhydroxylamine: a New Approach to the Selectivity
Eurasian Chemico-Technological Journal, 2002 A new approach to resolve the problem of selectivity with respect to N-phenylhydroxylamine in nitrobenzene hydrogenation is proposed. N-phenylhydroxylamine only is the final product of nitrobenzene electroreduction in aprotic media.

Determination of Enantiomeric Excess in Confined Aprotic Solvent
ACS ElectrochemistryThe validation of the stereochemical purity of synthesized compounds is a requisite for the fine-chemical industry, particularly in the production of enantiopure drug compounds. However, most methodologies employed in the determination of enantiopurity require carefully chosen chiral GC or HPLC columns, increasing associated cost, analysis time, and ...
