Oxidation of14C-nucleus-labeled bicreosol in aqueous-alkaline solution with oxygen

Abstract

Bicreosol, labeled in different ring positions (2.2 ′ or 3.3 ′ or 6.6 ′) with14C what is oxygenated in 0.25m-NaOH at 70 °. A number of low molecular fragments was isolated and their specific activities were determined. It was possible to show that most of the isolated acetone, formed by ring splitting, originates from ring-C-atoms 4 and 5 and the methyl group; the largest part of the isolated oxalic acid (formed in relatively small amounts) derives from ring-C-atoms 2 and 3, which are mainly split off as CO2.

Summary

Bikreosol (2,2'-dihydroxy-3,3'-dimethoxy-5,5'-dimethylbiphenyl), specifically in different ring positions (2,2 'or 3,3' or 6,6 ') with14C marked was at 70 ° in 0.25m-water. NaOH oxidized with oxygen; a number of low molecular weight fragments were isolated and their specific Activities determined. It could be shown that acetone formed by ring breakage originates mainly from ring positions 4 and 5 and the methyl group; Oxalic acid, which is formed in a relatively small amount, arises for the most part from the ring carbon atoms 2 and 3, but mainly as CO2 be split off.
