Abstract The dipole moments of the tetracyclopentadienides, Au(C5H5)4, of the lighter actinoids thorium, uranium and neptunium were measured in benzene solution. Although the compounds in the solid state have a quasi-Td molecular symmetry their dipole moments are not zero, owing to lowering of the molecular symmetry. The origin of the non-zero dipole moments is discussed.

The reaction of [Cp3ThCl] with in situ generated 1-lithium-3,3-diphenylcyclopropene results in the formation of [Cp3Th(3,3-diphenylcyclopropenyl)] (1), in good yields. Thermolysis of 1 results in isomerization to the ring-opened product, [Cp3Th(3-phenyl-1H-inden-1-yl)] (3) via a hypothesized carbene intermediate. This transformation represents a new mode of reactivity of 3,3-diphenylcyclopropene with
