Compounds where R1R2R3R4 = hydrocarbon (1-18C) abcd = 0 or 1 Y = chalcogen, esp O or S A = OH, hydrocarbyloxy, hydrocarbyl or OM M = alkali metal. - Insecticides, fungicides, & sequestering agents. - A solution of 32.6 g (IIe a=b=c=d=0, X=X'=Cl, A=OH, in 70g water was added dropwise to a refluxing solution of 140g water containing 40g NaOH. Addition took 1 hour and the mixture was then refluxed for 16 hours. 59ml 37% HCl was added and the mixture evaporated. 200ml 37% HCl was then added and the mixture filtered. The filtrate was evaporated to give 23g (I).
