A novel method for the highly selective synthesis of dissymmetric S,O-malonates starting from symmetric diphenyl dithiomalonates under neutral conditions is described. The key step is the thermal formation of an acylketene, the stability of which would contribute to the selectivity. The synthetic utility of the dissymmetric S,O-malonates is also shown.

Abstract Direct fluorination of malonic esters with a reagent system of iodosylbenzene and Et3N·5HF gave the corresponding 2-fluoromalonic esters in good to high yields. Direct chlorination using iodosylbenzene and hydrochloric acid also provided the 2-chloromalonates in high yields. Direct fluorination of malonic esters with a reagent system of iodosylbenzene and Et3N·5HF gave the corresponding 2-fluoromalonic
