Abstract

The preparation of two η⁶-estra-1,3,5(10),6-tetraene tricarbonylchromium complexes 4 and 6 are described. In both cases only one stereoisomer can be isolated, in contrast to other estrane-tricarbonylchromium complexes, where complexations are non-stereoselective. X-ray crystal structural analysis of 4 discloses that only the more sterically hindered β-facial isomer is formed. It is assumed that the 6,7-olefinic moiety exerts a directive influence on the complexation.
