thioisocyanate, carbon disulfide, and phenyl azide to give various monoinsertion products, in which the unsaturated bond inserted into one of the M–Ccage bonds, resulting in the formation of heterocycles. However, these metal–carboryne complexes did not show any reactivity toward pyridines, alkynes, and alkenes. The results clearly indicated that [η2-R2C(NR1)2]2M(η2-C2B10H10) shared some common properties with Cp2Zr(η2-C2B10H10)
