It′s all about the timing: Precisecontrol of the residence time (tRx; see picture) of reactive intermediates in flowmicroreactors enables the reaction pathway of lithiated 1,2‐dichloroethene to be switched to produce either alkenes or alkynes. This method also allows versatile syntheses of asymmetric disubstituted dichloroalkenes and alkynes.
一切都与时间有关:精确控制流式微反应器中反应中间体的停留时间(t R x;参见图片),可将锂化1,2-二氯乙烯的反应路径转换为产生烯烃或炔烃。该方法还允许不对称二取代的二氯烯烃和炔烃的通用合成。
