Superflash! Flash chemistry enables the use of highlyreactive unstable species as catalysts for chemical synthesis. Fast micromixing of a solution of [Pd(OAc)2] and that of tBu3P in 1:1 mole ratio gave a solution of a highlyreactive unstable species, which was immediately transferred to a vessel by using a flowmicroreactor, in which Suzuki–Miyauracoupling was conducted (see scheme).
超级快闪!快速化学使得能够使用高反应性的不稳定物质作为化学合成的催化剂。以1:1的摩尔比快速混合[Pd(OAc)2 ]溶液和t Bu 3 P溶液,得到了高反应性不稳定物质的溶液,该溶液立即通过使用流动微反应器转移到容器中。进行了Suzuki-Miyaura耦合(请参阅方案)。

continuous‐flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three‐step metalation, zincation, and Negishi cross‐coupling sequence, providing efficient access to a variety of functionalized 2‐fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous‐flow technology

complements transition-metal-catalyzed direct arylation and allows access to structures that are not easily accessible via other direct arylation methods. The reactions are highly functional-group tolerant, with alkene, ether, dimethylamino, trifluoromethyl, ester, cyano, halide, hydroxyl, and silyl functionalities compatible with reaction conditions.
