Bicyclic Dienes

A new class of bicyclic dienes which contain a σ plane of symmetry are efficiently prepared in a diastereoselective fashion using ring closing metathesis reactions. These molecules have potential as starting materials for a wide range of organic targets.Key words: metathesis, catalysis, stereoselective, decalin, desymmetrization.

Sulfur Bond

A nickel-catalyzed carbon-sulfur bond metathesis has been developed to access high-value thioethers. 1,2-bis(dicyclohexylphosphino)ethane (dcype) is essential to promote this highly functional group tolerant reaction. Further, synthetically challenging macrocycles could be obtained in good yield in an unusual example of ring-closing metathesis which does not involve alkene bonds. In-depth organometallic studies support a reversible Ni(0)-Ni(II) pathway to product formation. Overall, this work does not only disclose a more sustainable and more functional group tolerant alternative to previous catalytic systems based on Pd, but also presents new applications and mechanistic information which are highly relevant to the further development and application of unusual single bond metathesis reactions.
