Dc. Vanbeelen et al., CYCLIC ORGANOLEAD COMPOUNDS .4. SYNTHESIS AND MULTINUCLEAR NMR PROPERTIES OF 6-MEMBERED HETEROCYCLIC ORGANOLEAD COMPOUNDS, Silicon, germanium, tin and lead compounds, 20(1), 1997, pp. 37-45
Several six-membered heterocyclic organolead compounds were synthesize
d from the appropriate di-Grignard resp. organodilithio compounds and
a (diorgano)lead dihalide. The compounds were investigated by multinuc
lear NMR spectroscopy. Variable temperature H-1 NMR measurements revea
led a conformational equilibrium. In the C-13 and Pb-207 NMR spectra s
pecific effects caused by the presence of a lead atom in the ring syst
em could be observed.
