The reaction of testosterone-17gacetate (3) with heptailuorobutyric anhydride in high purity and anhydrous acetone at room temperature leads to the preferential formation of 1 with less than 1% of the isomeric 2,4-diene. The reaction is pseudo-unimolecular and after 30 min, 99% of the starting mater
