资源简介：
A nickel-catalyzed
three-component hydrocarboxylation of diynes
with ZnEt2 and CO2 (1 atm) is disclosed. With
this method, symmetric/nonsymmetric diynes could be reacted smoothly
with very high stereo- and regioselectivity, affording conjugated
2,4-alkadienoic acids incorporated with five- or six-membered rings
efficiently. A stepwise non-oxidative cyclometalation mechanism was
proposed based on careful mechanistic studies.
