Procedure

A mixture of 1,1,1-triethoxyisobutane (27.5 g, 0.14 mol) and aluminium t-butoxide (30 g, 0.12 mol) was heated at 170° C. for 1 hour during which time t-butanol distilled off. The residue was distilled at 100°-130° C. (atomosphere pressure) to afford 12.1 g (58%) of 1,1-diethoxy-2,2-dimethylethylene (Formula III: R2 =R3 =CH3 ; R4 =R5 =OC2H5), as a clear oil.
