High-resolution reaction time control in flow microreactors enables the reaction-pathway switching of trichlorovinyllithium generated by the H/Li exchange of trichloroethene. The method was successfully applied to the synthesis of 1,1,2-trichloroalkenes, 1-chloroalkynes, and unsymmetrically disubstituted ethynes.
