The unique nature of this activation is indicated by the fact that in the presence of 10 mol. % of Lewis acids such as BF<sub>3</sub> ⋅ Et<sub>2</sub>O, Me<sub>3</sub>SiCl, InCl<sub>3</sub>, and SnCl<sub>4</sub>, the reaction with 5-decyne does not occur even after 5 h, while in the presence of AlCl<sub>3</sub>, homocoupling products are selectively formed in high yield in 10 min at room temperature.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257551672560">Впервые обнаружен активирующий эффект AlCl<sub>3</sub> в количестве 10 мол. % в реакции гомо-сочетания алкил-, фенил- и силилзамещенных ацетиленов с системой реагентов Mg–Cp<sub>2</sub>ZrCl<sub>2</sub>.
