Abstract
Preparation procedure for 17 beta -hydroxy-17 alpha-vinyl- 14-androstadiene-311-dione increase characterized by catalytically reducing the 17 beta-hydroxy-17 alpha-ethynyl- 14-androstadiene-311 dioneal increase corresponding vinyl derivative effecting the reduction in the presence of a catalyst consisting of palladium on a support constituted by the carbonate of an alkaline-earth metal operating in homogeneous solution and at ordinary temperature and pressure.
