Plumbacyclopentadienylidenes, in which the lead atoms have divalent states and are coordinated by THF, pyridine and N-heterocyclic carbene, were synthesized and characterized. The THF-and pyridine-stabilized compounds can be regarded as rare examples of hypervalent 10-X-4 species. The equilibrium between the THF adduct and the free plumbacyclopentadienylidene was evidenced by spectroscopic analysis and theoretical calculations. The THF adduct in benzene converted into a plumbylene dimer, where one of the lead centers is coordinated by THF and the other lead atom is coordinated by a divalent lead atom, the dimer gradually decomposing into spiroplumbole. The THF adduct unexpectedly reacted with trifluoroborane and trichlorogallane to afford fluoroborole and chlorogallole, which are the first examples of non-annulated fluoroborole and gallole, respectively. Plumbacyclopentadienylidenes, in which the lead atoms have divalent states and are coordinated by THF, pyridine, and an N-heterocyclic carbene, were synthesized and characterized. The THF-stabilized compound can be regarded as a rare example of hypervalent 10-X-4 species, which converts into a plumbylene dimer and reacts with trifluoroborane and trichlorogallane to afford the corresponding fluoroborole and chlorogallole, respectively (see scheme; R=Me2tBuSi). © 2013 WILEY-VCH Verlag GmbH & Co.
