Abstract
The hexacarbonyl dicobalt complex of the acetylene thioether derived f rom (2R)exo-10-(methylthio)-2-bornanethiol has been prepared in good y ield. This compound affords a stable internally chelated pentacarbonyl complex either by thermal or oxidative decarbonylation. Optimal condi tions for the highly diastereoselective reaction of the chelated speci es have been developed. (C) 1997 Elsevier Science Ltd. All rights rese rved.
