Abstract
PURPOSE: To obtain the titled compound useful as an agricultural chemical, etc. free from by-products in good selectivity and yield, by reacting a halonitrobenzene with an alkali metal compound in a polar organic solvent in the presence of both nitrite ion and a metal copper or a copper compound.
CONSTITUTION: A compound shown by the formula I [X is halogen; R is H, 1W10C branched chain alkyl, R'O-(R' is 1W10C branched chain hydrocarbon), etc.; n is 1W2; m is 1W4, and when m is ≥2, R is the same or different] is reacted with an alkali metal compound (e.g., Na2CO3, K2CO3, Li2CO3, etc.) in a polar organic solvent (e.g., sulfolane, DMS, N,N-DMF, etc.) in the presence of nitrite ion, to give the titled compound shown by the formula II. In the reaction, besides the alkali metal compound, a metal copper or copper compound (e.g., cuprous chloride, cupric chloride, etc.) is added to the reaction system. Advantageously the filtrate comprising the polar organic solvent can be used directly in the following reaction.
