Anwendungen

Catalyst for isomerization and hydrosilyltion of unsaturated compounds. Co-catalyst for oligomerization/cyclooligomerization or polymerization of alkenes, Bis(1,5-cyclooctadiene)nickel(0) is used as a catalyst for the cycloaddition of 1,3-dienes and used to catalyze the addition of allyl phenyl sulfide to alkynes leading to 1,4-dienes. It is involved as a catalyst for asymmetric alpha-arylation and heteroarylation of ketones with chloroarenes, stereoselective borylative ketone-diene coupling, cycloaddition of benzamides with internal alkynes and methyl carboxylation of homopropargylic alcohols.

Bemerkungen

Air, light and moisture sensitive. Incompatible with strong oxidizing agents.
