reacted with ethyl vinyl ether to consistently produce pyran containing bicyclic adducts Decahydroquinoline (1), 4-pyridone (2), Pumiliotoxin C (3), of the same experiment also showed enhanced integration of the t-butoxy 9H proton However, heating the mixture to 75o C in a sealed pressure tube for 24h did result in

24 juil 2006 · 3-sulfolene will be heated to produce 1,3-butadiene and SO2 gas The 1,3- butadiene will be reacted with maleic anhydride to produce

Balmer 1 Introduction: The purpose of this experiment is to carry out a Diels- Alder reaction of 1,3- O O + FIGURE 1 The decomposition of 3-sulfolene to produce 1,3-butadiene so the mixture had to be heated before finishing the transfer

[PDF] Diels-Alder Reaction

While the Diels-Alder reaction described as a cycloaddition, the thermal loss of sulfur dioxide from 3-sulfolene to give 1, 3-butadiene (shown in Figure 3) is described as a chelotropic reaction-those in which two µ-bonds are made or broken in concert to a single atom
