Joy and Challenges of Alkynylation of Arenes and Heteroarenes through Double C−H Functionalizations
Biswajit Panda
Abstract
Abstract A significant number of reactions have appeared in the literature regarding direct oxidative cross‐coupling of arenes and heteroarenes with terminal alkynes achieved through functionalization of C (SP 2 ) −H and C (SP) −H bonds to provide the corresponding alkynylated products. The delights and difficulties of the direct alkynylation have been discussed thoroughly to enlighten this growing area. More emphasis is given to the successful implementation and improvement of various protocols for this transformation. Wherever necessary, the uniqueness of the methods has been shown by highlighting the substrate scope, selectivity, yields along with mechanistic consideration.
