Ruefenacht, Kurt published the artcilePhosphoric acid esters and thiophosphoric acid esters with some heterocyclic substitutions. 7. Thio- and dithiophosphoric acid esters of the GS 13005 type with some analog or homolog heterocyclic rings, Product Details of C3H3Br2ClO, the publication is Helvetica Chimica Acta (1973), 56(7), 2186-204, database is CAplus.
Analogs of the pesticide GS 13005 were prepared, including pyrazolinones of the type I, (R = Cl, OH), pyrazoles II, (R = H, Me, Cl; R1 = H, Cl, Br, NO2; R2 = H, Me, iso-Pr; R3 = Cl, OH), pyridazinones III, (R = H, Cl, Br, Me, Et; R1 = H, Cl, Me; R2 = H, Cl, Me; R3 = Cl, OH), thiadiazinones IV, (R = Me, Et; R1 = Cl, OH), and their mono- and dithiophosphates. The preparation, of analogous thiadiazepinones failed, giving instead pyrazolidinone derivatives Approx. 100 compounds were prepared
