Abstract : Dichlorocyclopentadienylborane was obtained from the reaction of sodium cyclopentadienide with boron trichloride. Placement of the double bonds is probably 1,3 from available nuclear magnetic resonance data. Butyl lithium removes a proton from the cyclopentadienyl ring to give the aromatic Cl2B-C5H4(-) anion. Attempts to remove chloride ion from dichlorocyclopentadienylborane to form a B-chloro derivative of the nido C5BH6(+) resulted, instead, in a polymeric decomposition. (Author)
