Ball mill synthesis: Cu(OH)2 (0.21g, 2.15 mmol) and benzene-1,3,5-tricarboxylic acid (0.29g, 1.37 mmol) were added to a 25 mL steel ball mill jar with a steel 13.6 g ball bearing, followed by MeOH (0.5 mL). The mixture was milled for 15 min at 25Hz. The obtained solid was washed with EtOH (3 x 20 mL) and dried in air.

  • Electro‐Mechanochemical Atom Transfer Radical

    The formation and regeneration of active Cu I species is a fundamental mechanistic step in copper‐catalyzed atom transfer radical cyclizations (ATRC). Typically, the presence of the catalytically active Cu I species in the reaction mixture is secured by using high Cu I catalyst loadings or the addition of complementary reducing agents. In this study it is demonstrated how the piezoelectric ...
