<p><b>New page</b></p><div>The part of TPP molecule that is most commonly involved in reactions is the thiazole ring, which contains [[nitrogen]] and [[sulfur]]. Thus, the thiazole ring is the "reagent portion" of the molecule. The C2 of this ring is capable of acting as an [[acid]] by donating its [[proton]] and forming a [[carbanion]]. Normally, reactions that form carbanions are highly unfavorable, but the positive charge on the tetravalent nitrogen just adjacent to the carbanion stabilizes the negative charge, making the reaction much more favorable. A compound with positive and negative charges on adjacent atoms is called an [[ylide]], so sometimes the carbanion form of TPP is referred to as the "ylide form".</div>FuzzyBot
