Surmary: An opposite stereoselectivity is observed in the r&cticn of 3d-hydroxy-5j%7-oxo-cholaic acid by alkali notals and by sodiun dithicnite, ccntraty to the results reported' with other cyclic or bicyclic ketones. An electrartrznsfer mechanism follmed by coupling of the ketyl radical with SOI is
a-Radicals, generated by decomposition of the initially formed radicalanion, have been postulated as intermediates in the electrochemical reduction of some aryl halides. 1 Evidence for such intermediates can be obtained by intramolecular trapping experiments and we have used a second benzene ring as
