Abstract
1380976 Preparation of organic carbonyl Compounds ROUSSEL UCLAF 28 June 1972 [1 July 1971] 30207/72 Headings C2C and C2U Organic carbonyl group containing compounds are prepared by oxidizing a compound containing an oxidizable hydroxy group in the liquid phase by reaction with silver silicate. Starting from their respective hydroxy derivatives, the following compounds are prepared in the examples: 9-oxo-xanthene; 1,2- dioxo – 1,2 – bis – (p – methoxyphenyl) – ethane; 1,2 – dioxo – 1,2 – bis – (phenyl) – ethane; 3,4- methlenedioxy-benzaldehyde; benzoquinone; naphtho – 1,4 – quinone; 3 – methoxy – estra- 1,3,5 – trien – 17 – one; 3 – oxo – cholestane; 5# – androstan – 3 – one; and 5α – pregnane- 3,20-dione.
