Reaction Conditions:
with iron(II) chloride tetrahydrate;tert-butylhypochlorite at 20; for 3 h;Inert atmosphere;chemoselective reaction;Reagent/catalyst;
Steps:
4.2. Preparation of mono- and difluorobenzyl chlorides. 4.2.1. General procedures. Method B.
General procedure: The reactions were carried out in a glass reactor (V=20 mL) with continuous stirring at room temperature. The tube under argon was charged with FeCl2·4H2O (0.18 mmol, 0.036 g), synthesized authentic tert-butyl hypochlorite [22] (54 mmol,5.88 g) and fluorotoluene 1-3 (18 mmol, (2.00 g) (or difluorotoluene 4-6 (2.30 g)). The mixture was stirred at r.t. for 3 h. After completion of the reaction, the reaction mixture was filtered through a paper filter. The target product was separated from the initial mono- or difluorotoluene by vacuum distillation.
