A Remarkable Catalytic Activity of [Cu(Ncme) 2 (PPh 3 ) 2 ]BF 4 in Conjugate Addition of Organomanganese Reagents to α,β-Unsaturated Ester,Enone and Allyl Chloride
A simple and convenient method of conjugate addition of alkyl and aryl organomanganese reagents to α,β-unsaturated ester and enone and allyl chloride in presence of Cu(I) salts is described. Conjugated products result with [Cu(NCMe)2(PPh3)2]BF4 as a catalyst along with chlorosilane as an accelerator at −10 to 0 °C.
