Abstract
As it is now presented in this publication, the discussion on the corrin nucleus is somewhat different in content from the discussion that occurred on 4 June 1964. There were then a number of short contributions on alternative approaches to the syntheses of the B 12 vitamins from that adopted by Eschenmoser and his co-workers; these will in due course be published elsewhere. In their place, it has been possible to include here the crystallographic examination of the structure of the cobalt ‘pseudo-corrin’ complex obtained during the synthetic experiments. It is also possible to see now relations between the different experimental results described which were not immediately obvious to us at the time of the Discussion Meeting.
