Description

Application

Reactant for:

• Oxidative addition reactions

Catalyst for:

• Asymmetric α-arylation and heteroarylation of ketones with chloroarenes
• Cross-coupling reactions
• Regioselective and stereoselective carboxylation/cyclization of allenyl aldehydes under a carbon dioxide atmosphere
• Methyl carboxylation of homopropargylic alcohols
• Stereoselective borylative ketone-diene coupling
• Cycloaddition of benzamides with internal alkynes

Catalyst for the cycloaddition of 1,3-dienes.

Used to catalyze the addition of allyl phenyl sulfide to alkynes leading to 1,4-dienes. The reaction with terminal acetylenes proceeds in high yield and high selectivity. A variety of functional groups are tolerated.
