## Abstract 1. The photochemical reactivity of testosterone (**1**) is strongly influenced by the nature of the solvent. Dimerization (→**18**), pinacone formation (→**19**)), reactions between the steroid and the solvent molecules (→**20a**, **20b**, **21**) and stereospecific isomerizations (→**2

## Abstract The UV.‐isomerisation of 11‐oxo‐14β,17α‐pregnane **9** to the 11,19‐cyclo‐derivative **11** is described. In addition the Pb(OAc)~4~‐fragmentation of photoproduct **11** was investigated. **11** yielded besides the expected 11‐oxo‐19‐hydroxy‐pregnane **18** the novel 9,11‐seco‐11,19‐cyc
## Abstract The irradiation of 3‐oxo‐10β‐hydroxy‐17β‐acetoxy‐Δ^1;4^‐estradiene (**2**) in dioxane solution with predominantly monochromatic light (2537 Å) yields a mixture of 17‐O‐acetyl‐estradiol (**3**) and the diketone **4**. The latter ist structurally related to products previously obtained by
