    摘要: A process for producing 6-phenoxypicolinic aldehydes, which comprises reacting a 2-halogeno-6-phenoxypyridine represented by the general formula I: ##STR1## where X is a halogen atom, Y is independently an alkyl group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms substituted by a halogen atom, an alkylthio group of 1 to 4 carbon atoms, a trifluoromethyl group, a fluorine atom or a chlorine atom, Z is a hydrogen atom or a fluorine atom, and n is an integer of 0 to 2, with magnesium metal, and then with a formylating reagent. These compounds are used as intermediates for the synthesis of insecticides.
