New technology has been developed that enables Suzuki-Miyaura couplings involving widely utilized MIDA boronates to be run in water as the only medium, mainly at room temperature. The protocol is such that no organic solvent is involved at any stage; from the reaction through to product isolation. Hence, using the E factor scale as a measure of greenness, the values for these cross-couplings approach
已经开发出的新技术使 Suzuki-Miyaura 联轴器包括广泛使用的 M
IDA 硼酸盐,可以在作为唯一介质的
水中运行,主要是在室温下。该协议在任何阶段都不涉及有机溶剂;从反应到产物分离。因此,使用 E 因子尺度作为绿色度的度量,这些交叉耦合的值接近于零。
