D’yachenko, E. K. published the artcileFormamidines. Benzo-2,1,3-thia(selena)diazoles, Computed Properties of 30536-19-7, the publication is Zhurnal Organicheskoi Khimii (1987), 23(11), 2450-4, database is CAplus.
The title formamidines I (R1 = H, R2 = H, Me; R1 = Cl, R2 = H, Cl; R1 = Me, R2 = H, Cl; R1 = R2 = Br) were prepared in 40-86% yields by Vilsmeier reaction of the corresponding amines with POCl3-DMF in benzene or by reaction with HCO2H in the presence of hexametapol. Addnl. obtained were 78-87% formamidines II (R3 = H, Me, Cl) and 72% selenium derivative III. All compounds possessed acaricidal activity but were less active than halekron.
