-

Yield:622-95-7 86% ,104-83-6 6%

Reaction Conditions:

with tetra-N-butylammonium tribromide;1,3-dichloro-[1,3,5]triazinane-2,4,6-trione in dichloromethane at 20; for 2 h;Photolysis;Time;Reagent/catalyst;Concentration;

Steps:

13 Halo-de-carboxylation of 4-chlorophenylacetic acid chloroisocyanurate/brominating agent
General procedure: A mixture of 4-chlorophenylacetic acid (1 mmol), chloroisocyanurate, brominating agent and solvent (6 mL) was stirred under fluorescent room light irradiation (FL). An aliquot of the reaction mixture washed with 1 M aq Na2S03, dried over Na2S04, and filtered through short neutral silica gel pad. The yields of 4-chlorobenzyl bromide and chloride, and 4-chlorobenzal bromide were determined by gas chromatography (GC) using 1,2,4-trichlorobenzene as internal standard. The results are presented in Table 9
