A Case of the Benz Part I

The following posts report on the three step synthesis of benzilic acid from benzaldehyde. The first step is the conversion of benzaldehyde to benzoin using a vitamin, thiamine, as a catalyst. In the second step, the benzoin is oxidized to benzil through the use of an oxidizing agent. The third step is the preparation of […]

What’s the Diels? Part II

The Diels Alder reaction between furan and maleic anhydride typically it done in THF. The nice thing about this solvent is that the product crystallizes in the reaction media over the course of a week and can be filtered to recover an essentially pure product. My hypothesis was that changing the solvent may influence the […]

What’s the Diels? Part I

This year we preformed the Diels Alder reaction between maleic anhydride and furan. There are many Diels Alder reactions to choose from when planning an organic chemistry lab. I chose this one because it has an interesting history. Diels and Alder concluded that the endo product had been formed when they reported the reaction in […]
