We have developed a catalytic method for the hydroalkylation of allenes using alkyl triflates as electrophiles and silane as a hydride source. The reaction has an excellent substrate scope and is compatible with a wide range of functional groups, including esters, aryl halides, aryl boronic esters, sulfonamides, alkyl tosylates, and alkyl bromides. We found evidence for a reaction mechanism that involves
我们已经开发了一种催化方法,用于使用烷基三氟甲磺酸酯作为亲电子试剂和硅烷作为氢化物源的丙二烯加氢烷基化。该反应具有优异的底物范围,并且与各种官能团相容,包括酯,芳基卤化物,芳基硼酸酯,磺酰胺,烷基甲苯磺酸盐和烷基溴化物。我们发现了一种反应机制的证据,该反应机制涉及不寻常的双核铜盟友配合物作为催化中间体。这些配合物的异常结构为其意外的反应性提供了理论依据。
