β-chlorophenone with alkanes using 2-(tert-butylperoxy)-2-methylpropane as the oxidant and 2,2′-bipyridine as the catalyst was reported. A variety of β-chloropropiophenones were tolerated, leading to the alkylated products in moderate to good yields. Preliminary mechanistic studies suggested that the in situ formed quaternary ammonium salt activated unsaturated ketone, leading to the alkyl-alkyl cross-coupling
报道了使用2-(叔丁基过氧)-2-甲基丙烷作为氧化剂和2,2'-联吡啶作为催化剂的β-氯苯酮与烷烃的新型Csp 3 -Csp 3偶联反应。可以耐受多种β-氯代苯丙酮,导致烷基化产物的收率适中至良好。初步的机理研究表明,原位形成的季铵盐激活了不饱和酮,导致了烷基-烷基交叉偶联产物。
