Transmetalation of carborane-fused zirconacycles to Cu(II) induces the C-C coupling reaction to form four-membered rings. This serves as a new efficient and general methodology for the generation of a series of carborane-fused cyclobutenes and cyclobutanes. A reaction mechanism involving transmetalation to Cu(II) and reductive elimination is proposed.
