A new and efficient process for organic synthesis in aqueous media based on a direct ohmic heating reactor is described. Four representative organic transformations, a Diels–Alder cycloaddition, a nucleophilic substitution, an N-alkylation and a Suzuki cross-coupling reaction, were performed using this process. The results, when compared with those obtained under conventional external heating (oil bath) and microwave heating, showed that ohmic reactor allows faster and more uniform heating and an induced increase of dynamics/mobility of charged species leading in several cases to higher reaction yields and shorter reaction times.

水相有机合成新且高效的工艺。使用该工艺进行了四种代表性的有机转化,包括Diels-Alder环加成、亲核取代、N-烷基化和铃木交叉偶联反应。与常规外部加热(油浴)和微波加热的结果相比,欧姆反应器能够实现更快且更均匀的加热,并诱导带电物质的动力学/流动性增强,从而在多个案例中获得更高的反应产率和更短的反应时间。
