Aims: Review on alkyn/alkene carbonyl metathesis reaction.
Background: Green approach in organic synthesis.
Objective: An overview of exploration of the metathesis reactions with high atom-economy as well as environmentally and ecologically benign reaction conditions.
Method: Literature review.
Result: Alkyne-carbonyl and alkene-carbonyl metathesis reactions will have more contributions to the fields of modern organic chemistry in future.
Conclusion: The progress of the alkyne-carbonyl metathesis for the synthesis of different types of heterocycles/carbocycles is thoroughly discussed in detail.
