applied to the synthesis of symmetrical butadiynyl (32―37), octatetraynyl (47) and do-decahexaynyl (49) polyynes. The unsymmetrically substituted diynes 39, 40 and 41 and triynes 43 and 44 were synthesized by coupling reaction between the newly synthesized bromoalkyne/diynes 38/42 and commercially available (trialkylsilyl)acetylenes. Syntheses of the 1,2,3-triazolyl-C-nucleoside analogue 51 and of the
