摘要

Intramolecular addition of heterofunctionalities to CC double bonds without β-hydride elimination was investigated and catalyzed by ruthenium complexes. The combination of RuCl3· nH2O (10mol%) and 3equiv. of AgOTf acted as a catalyst for cyclization of 2- allylphenol (1a) to 2, 3-dihydro-2-methylbenzofuran (2a) in good yield in the presence of Cu (OTf) 2 as a co-catalyst and PPh3 as a ligand. This catalyst system also catalyzed the ...
