Reaction Steps

Diethyl 2-vinylcyclopropane-1,1-dicarboxylate (5 g; 0.024 mol) was combined with 8.8 g (0.047 mol) tosyl hydrazine in 20 mls diglyme and the mixture heated with agitation to reflux for one hour. The reaction mixture was then allowed to cool and 2.73 g crude product obtained after washing with water and petroleum ether. The purified diethyl 2-ethylcyclopropane-1,1-dicarboxylate, obtained by distillation, contained 61.89% carbon and 8.33% hydrogen (calculated 61.66% C, 8.47% H) and the nuclear magnetic resonance spectra verified that the product was completely reduced.
