title: Direct observation of oxidative cyclization of eta2-alkene and eta2-aldehyde on Ni(0) center. Significant acceleration by addition of Me3SiOTf.
abstract: Direct oxidative cyclization of (eta2:eta2-CH2=CHCH2C6H4CHO)Ni(PR3) to form the nickelacycle and drastic acceleration of the cyclization by the addition of Me3SiOTf were observed. (eta2-PhCHO)Ni(PCy3)2 also reacted with Me3SiOTf to give (eta1:eta1-Me3SiOCH(Ph))Ni(PCy3)OTf.
