included 4-[[(aryloyl)amino]methyl]phenoxy, 4-(arylacetamido)phenoxy, and 4-[[(arylamino)carbonyl]methyl]phenoxy. A total of 20 compounds were synthesized and tested. Structure-activity relationships are presented. Several of the new compounds were found to be strong allosteric effectors of hemoglobin. The two most active compounds are 2-[4-[[(3,5-dichloroanilino)carbonyl]-methyl]phenoxy]- 2-methylpropionic
A preparation, comprising a mixture of dibenzoyl peroxides where the mixture of dibenzoyl peroxides contains 50 to 99.7 mole % of a symmetric dibenzoyl peroxide and 0.3 to 50 mole % asymmetric dibenzoyl peroxides, shows a reduced decomposition temperature of the peroxides compared to the symmetric dibenzoyl peroxide and is suitable for hot cross-linking silicone rubber. The preparation can be produced by reacting a mixture containing a first benzoyl chloride and a second benzoyl chloride that is different therefrom with hydrogen peroxide, wherein the mixture of benzoyl chlorides contains 70 to 99.7 mole % of the first benzoyl chloride and 0.3 to 30 mole % of the second benzoyl chloride.

3,4-Dichlorbenzoylchlorid, 3,4,5-Trichlorbenzoylchlorid, 2,3,4,5-Tetrachlorbenzoylchlorid oder Pentachlorbenzoylchlorid werden in hoher Selektivität und hoher Ausbeute gewonnen, wenn man 4-Chlorbenzoylchlorid mit einem Chlorierungsmittel in Gegenwart eines Katalysators bis zum jeweiligen Chlorierungsgrad umsetzt.
Die genannten Polychlorbenzoylchloride sind Ausgangsmaterialien zur Herstellung von Farbstoffen und Schädlingsbekämpfungsmitteln.
