(hetero)aryl tosylates has been investigated employing an integrated continuous flow/batch protocol. The regioselective ortho metalation of (hetero)aryl tosylates using n-BuLi and ZnCl2 was effectively achieved using continuous flow chemistry in a short residence time of 10.92 s, without removal of the tosyloxy group. The Pd-catalyzed Negishi coupling reactions of various (hetero)aryliodides with the

The ortho-selective alkynylation of polyhalo-substituted (hetero)aryl tosylates was investigated using an integrated continuous-flow/batch protocol. Without the elimination of the tosyloxy group, the regioselective ortho-metalation of the (hetero)aryl tosylates employing n-BuLi and ZnCl2 was successfully achieved in continuous-flow chemistry within 10.92 s (residence time).
