The formation of benzothiazole-2-thiol from aniline, carbon disulphide and sulphur at 230ยฐC was shown to occur by a sequence of three principal steps. Labelling experiments confirmed that both sulphur atoms originate from carbon disulphide. An initial polar reaction to form thiocarbanilide via pheny
The following lines of evidence establish that oxime formation from pyruvic acid occurs with ratedetermining carbinolamine dehydration under acidic and neutral conditions. First, saturation effects observed at pH 7 are strongly suggestive of carbinolamine accumulation, requiring that dehydration of
