Application

Catalyst for the cycloaddition of 1,3-dienes.
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
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.

It is well known that, stemming from the mutual interplay between chromophores, circular dichroism (CD) is a powerful technique to deal with structural problems for both the small organic molecule and the biopolymer. However, quantitative interpretations of the spectroscopic and

Biodegradable polyesters with various tacticities have been synthesized by means of stereoselective ring-opening polymerization of racemic lactide and β-lactones but with limited side-chain groups. However, stereoselective synthesis of functional polyesters remains challenging from O-carboxyanhydrides that have abundant pendant side-chain functional

Csp2- and Csp-hybridized coupling reactions are established catalytic approaches. However, multi-step Csp3- and Csp2-coupling reactions of boronic acids and related derivatives are still limited by ineffective two-electron transmetalation reactions.

Nickel transition metal and its complexes can be used as a catalyst in many synthetic transformations, like oxidative addition, C-H activation, reductive elimination, oxidative cyclization, oligomerization, and in cross-coupling reactions.
