Abstract

Homocoupling of terminal alkynes proceeds using Co2(CO)8 pretreated with phenanthroline to give good yields of 1,3-diynes under mild conditions.

      Finally, the intermediate C involves in self-dimerization to obtain the desired product 2a. More surprisingly during our screening experiments (Table 1), we have observed that when, phenylacetylene (1a) was reacted in presence of catalytic amounts of TEMPO and KOtBu, the unexpected formation of 1,3-enyne product 3a was observed with higher E-selectivity (Table 1, Entry 12) [24]. This serendipitous finding was scrutinized and obtained the suitable optimal conditions (The additional optimization of reaction conditions are provided in SI).
