Tolclofos-methyl

This is apparently the only agrochemical manufactured from p-cresol. Two process routes have been established, both using 2,6-dichloro-p-cresol as a key intermediate. Sumitomo Chemical Co. Ltd., Japan is perhaps the only manufacturer of tolclofos-methyl with an annual production of 500 tons. 

6-dichloro-p-tolyl 0,0-dimethyl phosphorothionate 0,(2,6-dichloro-4-methyl-phenyl) 0,0 dimethyl phosphoro thioate Colorless crystals 

Uses Control of soil borne diseases caused by Rhizoctonia, Selerotium and Typhula SPP on Potatoes, Sugar-beet, cotton, peanuts, vegetables, etc. [26]. 

DNOC as a basic o-cresol derivative has been discussed in an earlier chapter. Some aspects of this multipurpose agrochemical, an insecticide, an acaricide, a herbicide and also a fungicide, are discussed here in some detail.

More than 100 organophosphate componnds show fnngicidal action however, relatively few are of practical nse as fnngicides. Among these few are iprobenfos and aluminium-fosetyl, which are systemic in their activity, and tolclofos-methyl, which acts as a protectant or contact fungicide.

Figure 2.160, which shows the EI/CI spectra of the phosphoric acid ester Tolclofos-methyl, is an example of this. The base peak in the FI spectrum shows a Cl atom, noticeable by the typical isotope pattern of m/z 265/267. Loss of a methyl group (M - 15)" gives m/z 250. Is m/z 265 the nominal molecular mass The Cl spectrum shows m/z 301 for a protonated ion so the nominal molecular mass could be 300 Da. A chlorine isotope pattern of two Cl atoms is also visible.
