Notes:
Isomeric mixtures of compounds MenM(CH=CHMe)4-n (M=Si, Pb; n=0-3) have been prepared and studied, as well as pure Me3M(CMe=CH2) and mixtures containing propenyl isopropenyl residues bonded to silicon and lead. 1H, 13C, 29Si and 207Pb NMR data are presented; as previously observed for the corresponding tin compounds, the 29Si and 207Pb shifts for the Me3MC3H5 isomers can be used to calculate the shifts expected for the other isomers; while for lead the agreement is good, calculated and observed values for silicon diverge with decreasing n due, at least in part, to steric factors.
