==Reactions== Furoin synthesis from furfural is also catalyzed by vitamin B1 (thiamine). In 1957, Ronald Breslow proposed that this reaction involves a relatively stable carbene form of thiamine. In the catalytic cycle shown below two molecules of furfural react to give furoin, via a thiazol-2-ylidene catalyst, resulting from loss of one proton at carbon 2 of the thiazolium cation of vitamin B1:
