ABSTRACT
The anionic monocarborane alkyne [12-(HC[triple bond, length as m-dash]C)-CB11H11]- was employed as a ligand towards Cu(i) to form terminal alkyne complexes. Spectroscopic methods and X-ray crystallography allowed for a detailed structural analysis of complexes with nitrogen ligands, which are the first examples featuring carborane-C[triple bond, length as m-dash]CH â metal π coordination. Addition of phosphines to compound 2 afforded homoleptic Cu(i) complexes [Cu(PR3)n]+ (4), in which case the carborane becomes a non-coordinating anion. Polymeric acetylide 5 was obtained in almost quantitative yield from 2 and proved to be a suitable precursor to heterobimetallic Cu(i)/M(ii) (M = Pd, Pt) alkynide complexes with side-on and end-on coordination to the metal centers.
