Abstract
Abstract A convenient synthetic method has been developed for accessing 2,6-dialkynyl-3,5-dichloropyridine derivatives in acceptable to good yields. The methodology involved ultrasound assisted site-selective alkynylation of 2,3,5,6-tetrachloropyridines under Pd/C Cu catalysis. A variety of terminal alkynes were employed in this C C coupling reaction to afford the corresponding 2,6-dialkynyl-3,5-dichloropyridine derivatives.
