Part I, the Friedel-Crafts acylation on DAA and methyl dehydroabietic acid was carried out with acetyl chloride, benzoyl chloride or phthalic anhydride as acylating regents, anh- ydrous aluminum chloride as catalyst and with different solvents to compare with, we have got t- hree new compounds.

第一部分，分别以脱氢松香酸和脱氢松香酸甲酯为底物，乙酰氯、苯甲酰氯、邻苯二甲酸酐为酰化试剂，无水三氯化铝作催化剂，采用不同的溶剂及反应条件进行傅克酰基化反应，得到3个新化合物。

The latter is chlorinated in the side chains under free-radical conditions to give 2,4-dichloro-5-fluoro-3-dichloromethyl-1-trichloromethylbenzene. The latter is hydrolysed via 2,4-dichloro-5-fluoro-3-dichloromethylbenzoic acid, which can be isolated if necessary, to give 2,4-dichloro-5-fluoro-3-formyl-benzoic acid, the aldehyde group of which is reacted to give 2,4-dichloro-5-fluoro-3-N-hydroxyiminomethyl-benzoic acid, from which, with simultaneous conversion of the carboxyl group into the chlorocarbonyl group, water is eliminated using an acid chloride to give the nitrile 2,4-dichloro-3-cyano-5-fluoro-benzoyl chloride.
