On March 28, 2019, Wailes, Jeffrey Steven; Briggs, Emma; Carter, Neil Brian; Morris, Melloney; Tate, Joseph Andrew published a patent.Related Products of 785777-98-2 The title of the patent was Preparation of pyrimidinyl carbamate or urea derivatives as herbicides. And the patent contained the following:
The present invention relates to herbicidally active pyridyl-(or pyrimidyl-) pyrimidine derivatives I [X1 = N or CR1; R1 = H, halo, CN, etc.; R2 = halo, CN, NO2, etc.; R3 = C(O)X2R12; X2 = O or NR10; R4 = H, alkyl, alkoxy, etc.; when X2 = O, R12 = alkyl, alkoxyalkyl, haloalkyl, etc.; when X2 = NR10, R12 = H, alkyl, alkoxy, etc.; R10 = (independently) H, alkyl, cycloalkyl; n = 0-1] or salts or N-oxides thereof, as well as to processes and intermediates used for the preparation of such derivatives E.g., a 2-step synthesis of II, starting from 2-chloro-4-methylpyrimidine-5-carboxylic acid, was described. Exemplified compounds I were evaluated for their pre-emergence and post-emergence herbicidal activities (data given). The invention further extends to herbicidal compositions comprising such derivatives I, as well as to the use of I and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants. The experimental process involved the reaction of 2,5-Dichloro-4-(trifluoromethyl)pyrimidine(cas: 785777-98-2).Related Products of 785777-98-2
