REDUKTION VON BENZOTRICHLORIDEN ZU BENZALCHLORIDEN
Baasner, B.,Klauke, E.
, p. 359 - 364 (1988)
Benzal chlorides are prepared from the corresponding benzotrichlorides by reduction with thiophenol in the presence of catalytic amounts of copper(I) bromide.
One-pot, selective and mild conversion of benzylic alcohols to gem -dichlorides using chlorodiphenylphosphine and 2,3-dichloro-5,6-dicyanobenzoquinone as a new and neutral system

A mild and one-pot conversion of benzylic alcohols to their corresponding gem-dichlorides is reported for the first time using chlorodiphenylphosphine (ClPPh2) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in dichloromethane under neutral conditions and at room temperature. The present method can be efficiently used for preparation of gem-dichlorides even in the presence of some other functional groups with excellent chemoselectivity.
MECHANISMS OF FREE-RADICAL REACTIONS. XIII. MECHANISM AND SELECTIVITY OF THE FREE-RADICAL HALOGENATION OF ALKYL AROMATIC HYDROCARBONS WITH FLUOROALKYL SUBSTITUENTS
Dneprovskii, A. S.,Eliseenkov, E. V.,Mil'tsov, S. A.
, p. 317 - 324 (2007/10/02)
The free-radical chlorination and bromination of 1-fluoro-2-arylethanes and 1,1,1-trifluoro-2-arylethanes was studied by the method of competing reactions.In all cases a good correalation between log krel and the Brown ?+ constants was observed.The variation of the selectivity in the transition from one reaction series to the other indicates that two independent factors which determine the reactivity (the change in the dissociation energy of the C-H bond and the polar effect of the substituents) have a simultaneous effect.
