Abstract

207Pb NMR spectra were used to determine the structure of adducts of triphenyllead chloride and diphenyllead dichloride in CH2Cl2 and CH3CN. The bases included several phosphorus donors, such as tributylphosphine, oxygen donors, such as tributylphosphine oxide, and nitrogen donors, such as pyridine. A number of bidentate bases were also studied. The 207Pb spectra indicate that rapid exchange occurs in the adducts, even at temperatures of -90 °C. The magnitude of the shift relative to the lead acid indicates that all of the bases, including the bidentate bases, form five-coordinate adducts with triphenyllead chloride. Diphenyllead dichloride forms six-coordinate adducts, except for the adduct with tributylphosphine, which is five-coordinate. This is the first report of a five-coordinate adduct of diphenyllead dichloride. Copyright © 2003 John Wiley & Sons, Ltd.
