ABSTRACT:
When the reaction of aldehydes with alkali metal trihaloacetates is carried out in the presence of a highly polar aprotic solvent (DMF, DMSO), novel organic alkali metal carbonates, which are precursors of pyrethroid insecticides, are formed in high yields and at a high rate. Novel sulfonates and dihalophosphites, derived from these carbonates have also been claimed.
