Co( iii )-catalysed regioselective linear C(8)–H olefination of isoquinolone with terminal aromatic and aliphatic alkynes

-2-one with terminal (aromatic and aliphatic) alkynes is reported under Co(III) catalysis. This is an exclusive report on the C8 functionalization of isoquinolone using non-noble transition metal complexes. Experimental and computational mechanistic studies have also been performed to depict the reaction pathway.
