Chemo and Enantioselective Butadiene-functionalized Dienes Cyclodimerization catalyzed by Nickel Complexes
摘要:
Chiral aminophosphine-phosphinite and diphosphine ligands induce chirality during nickel catalyzed cyclodimerization of conjugated dienic esters with butadiene. The enantiomeric excesses of the cyclodimers are determined by chiral GLC and NMR methods.
