1,2,4-Tris(trifluoromethyl)benzene: selective lithiation and subsequent electrophilic substitution

1,2,4-Tris(trifluoromethyl)benzene quant. undergoes a hydrogen/metal exchange when treated with an ethereal soln. of lithium 2,2,6,6-tetramethylpiperidide. Proton abstraction occurs concomitantly from positions 5 and 6, the ratios varying from 80:20 to 90: ...

Additivity of substituent effects in the fluoroarene series: equilibrium acidity in the gas phase and deprotonation rates in ethereal solution

Benzene and all mono-, di-, tri, tetra-, and pentafluoro-substituted derivs. thereof were equilibrated with the corresponding aryl anions in the gas phase. Perfect additivity of the substituent effects on the acidity was obsd. The basicities were diminishe ...

Periodic processing in continuous reactors

Albert Renken

Yields and selectivities of intermediate products of consecutive reaction in an continuous reactor are improved by making periodic changes in the concn. of the feed reactants in a sinusoidal or rectalinear manner and by using a mixing vessel equipped with ...
