title: Three-component [2+2+1] cross-cyclotrimerization of carboryne, unactivated alkene, and trimethylsilylalkyne co-mediated by Zr and Ni.
abstract: A three-component [2+2+1] cross-cyclotrimerization of carboryne, alkene, and trimethylsilylalkyne has been achieved under the cooperative action of zirconium and nickel, leading to the synthesis of a series of dihydrofulvenocarboranes. The bulkiness of the alkyne and phosphine ligand plays a key role in the selective formation of the products.
