additional confirmation of the positions of deuterium exchange in stilbestrols was obtained from an analysis of the oxidation of des-d8 to z , z-2,3',3 '' ,5,5',5 '' -hexadeuteriodienestrol ( beta-dies-d6 ) and of the hydrogen/deuterium exchange reaction of hexestrol ( hex ) to 3',3 '' ,5',5 '' -hexestrol , ( hex-d4 ) .
