title: Reduction-free synthesis of stable acetylide cobalamins.
abstract: A straightforward, reduction-free method for the synthesis of organometallic cobalamins has been developed. Stable phenylacetylide derivatives were characterized by X-ray analysis, showing a pronounced influence of the electronic nature of substituents on their structure.
