In the presence of Cu(MeCOCHCO2Et)2, acetophenone and benzalacetone trimethylsilyl enol ethers RC(OTMS):CH2 [R = Ph, 4-MeC6H4, 3-MeC6H4, 2-MeC6H4, 4-MeOC6H4, 4-FC6H4, 4-ClC6H4, 3-ClC6H4, 2-ClC6H4, 4-BrC6H4, 4-IC6H4, 4-F3CC6H4, 2-naphthyl, 2-furyl, 2-thienyl, 2-pyridinyl, 3-pyridinyl, (E)-PhCH:CH] underwent oxidative coupling with azobisalkanenitriles such as azobisisobutyronitrile (AIBN) mediated by Ag2CO3 in THF to yield γ-aryl-γ-ketonitriles such as RCOCH2CMe2CN [R = Ph, 4-MeC6H4, 3-MeC6H4, 2-MeC6H4, 4-MeOC6H4, 4-FC6H4, 4-ClC6H4, 3-ClC6H4, 2-ClC6H4, 4-BrC6H4, 4-IC6H4, 4-F3CC6H4, 2-naphthyl, 2-furyl, 2-thienyl, 2-pyridinyl, 3-pyridinyl, (E)-PhCH:CH] in 22-91% yields. Attempted oxidative coupling in the presence of bis(oxazolinyl)pyridines yielded products with no enantioselectivity.
