Isolation of cationic and neutral (allenylidene)(carbene) and bis(allenylidene)gold complexes

Author affiliations

Abstract

The one-electron reduction of a cationic (allenylidene)[cyclic(alkyl) (amino)carbene]gold(I) complex leads to the corresponding neutral, paramagnetic, formally gold(0) complex. DFT calculations reveal that the spin density of this highly robust coinage metal complex is mainly located on the allenylidene fragment, with only 1.8 and 3.1% on the gold center and the CAAC ligand, respectively. In addition, the first homoleptic bis(allenylidene)gold(I) complex has been prepared and fully characterized.
