| Abstract: | N′-Thioaroyl-N,N-dimethylformamidines undergo exchange of sulphur for oxygen on treatment with benzonitrile oxide, are hydrolysed to thioamides by ammonia, hydrazine and hydroxylamine, undergo S-methylation on treatment with methyl iodide, and react with -bromoketones and ketenes to give 5-aroylthiazoles and 6-oxo-6H-1,3-thiazines respectively. |
