Abstract Treated with lead tetraacetate in boiling benzene the saturated 19‐hydroxy steroids 9 and 16 gave complex mixtures containing products of fragmentation and of hydrogen abstraction from δ‐carbon atoms. This behaviour differs significantly from the preponderantly uniform fragmentation of the unsaturated alcohols 1 and 36 , which takes place already at room temperature and is ascribed to anchimeric acceleration by the homoallylic double bond.
