| Abstract | 2-Thienylacetylene (4a) and 3-thienylacetylene (4b) have been synthesised via the corresponding alkynols, 2-methylbut-3-yn-4-(2'-thienyl)-2-ol (3a) and 2-methylbut-3-yn-4-(3'-thionyl)-2-ol (3b) respectively using 2-methylbut-3-yn-2-ol (1) and bromothiophenes (2a and 2b). In the synthesis of 3b, self condensation of 1 takes place giving 2, 7-dimethylocta-3, 5-diyne-2, 7-diol (5) which in turn reduces the yield of 3b. A mechanism has been suggested for the diol formation. |
