摘要

An ultrasound-assisted synthesis of symmetrical 1, 3-diyne compounds with electron- withdrawing or-donating substituents is described and illustrated by the palladium-catalyzed homocoupling reaction of n-butyl alkynyltellurides. This procedure offers easy access to 1, 3- diynes in very short reaction times, and the products are achieved in good to excellent yields.
