[cyano, nitro, (non)enolizable ketone, chloride, and amide moieties] are allowed on methoxyarenes. Moreover, an array of alkanenitriles with/without an aryl moiety at the nitrile α-position can be employed. The system also features no requirement of a stoichiometric base, MeOH (not salt waste) formation as a byproduct, and the production of congested quaternary carbon centers.
有机超碱催化剂t -Bu-P4实现了烷烃前亲核体对甲氧基芳烃的亲核芳族取代。在甲氧基芳烃上可以使用各种官能团[氰基,硝基,(不可)烯化的酮,氯和酰胺部分)。此外,可以使用在腈α-位具有/不具有芳基部分的链烷腈的阵列。该系统还不需要化学计量的碱,不需要的副产物MeOH(无盐废料)形成以及拥挤的季碳中心的生产。
