A series of S-alkyl-N-phenylthiuronium picrates, styphnates and picrolonates has been prepared and the melting points determined. By use of these derivatives it is possible to identify any of the lower primary and secondary alkyl halides examined. This has not previously been possible with S-alkylthiuronium salts. The reaction between tertiary alkyl halides and thiourea has been re-examined.
已制备了一系列S-烷基-N-苯基硫代硫酸盐、硫代硫酸盐和硫代硝酸盐,并测定了它们的熔点。通过使用这些衍生物,可以鉴定所检测到的任何较低级别的一次和二次烷基卤化物。这以前在S-烷基硫代硫酸盐中是不可能的。三级烷基卤化物与硫脲之间的反应已经重新检查。
