The following papers are very important in the opinion of two referees.
Multiple and Highly Selective Alkyne–Isonitrile C−C and C−N Couplings at Group 4 Metallocenes
Selective but strange: The reactions of titano-, zircono- and hafnocene alkyne complexes with 2-xylyl isonitrile afford enamine complexes, aza-metallacycloallenes, and/or fused heterometallacycles, depending on the metal, the Cp′ ligand, and the stoichiometry applied. The alkyne always takes part in the coupling reactions. Furthermore, the metallocene is successfully expelled from the tricyclic complex to yield a highly functionalized pyrrole.
A Two-Component Alkyne Metathesis Catalyst System with an Improved Substrate Scope and Functional Group Tolerance: Development and Applications to Natural Product Synthesis
Ill-defined but well-behaved: Although oligomeric in nature, alkyne metathesis catalysts formed in situ by mixing of a trisamido molybdenum alkylidyne complex and an appropriate trisilanol were found highly tolerant of sensitive functional groups and protic sites. This notion is witnessed by the total syntheses of the sesquiterpene lactone manshurolide, the immunosuppressive cyclodiyne ivorenolide A, as well as by studies toward the quinolizidine alkaloid lythrancepine I (see scheme).
