  双环桥头亚磷酰胺配体和酸添加剂促进的钯催化的烯丙醇与N-杂环的脱水交叉偶联

  摘要：

  报道了使用钯催化的在烯丙基醇和N-杂环之间的温和且有效的脱水交叉偶联反应。双环桥头亚磷酰胺（briphos）配体与Pd（dba）2一起是高效催化剂，速率确定步骤中涉及的酸添加剂促进了催化循环。烯丙基醇与包括咪唑，苯并咪唑和三唑的N-杂环的偶合反应在温和的反应条件下进行，使用钯/硫磷和五氟苯酚的收率很高。

  The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.

  A mild and efficient dehydrative cross-coupling reaction between allylic alcohols and N-heterocycles using palladium catalysis is reported. A bicyclic bridgehead phosphoramidite (briphos) ligand together with Pd(dba)2 is a highly efficient catalyst, and an acid additive involved in the rate-determining step promotes the catalytic cycle. The coupling reaction of allylic alcohols with N-heterocycles
