A process is provided for producing a thiosemicarbazide which includes the steps of reacting an alkylamine with carbon disulphide in the presence of a base selected from N,N-diisopropylethylamine and N,N,-diisopropyl-methylamine to produce an intermediate and converting the intermediate into the thiosemicarbazide. The process has particular application to producing 4-methyl-3-thiosemicarbazide, an intermediate useful in producing the broad-spectrum herbicide tebuthiuron. |
