The invention pertains to a method in which a halogen atom of an organic compound is replaced with a group derived from a nucleophilic agent, at high yield and high efficiency, by the following method which includes a step of reacting the nucleophilic agent with an organic material having a halogen atom bonded to a carbon atom having four σ bonds, more specifically: a method for producing an organic compound having Q, the method including a step of reacting a compound represented by general formula (2) with an organic starting material having at least one halogen atom bonded to a carbon atom having four σ bonds so as to replace the halogen atom in the organic starting material with Q:
MQa (2)
(wherein M represents an alkali metal atom, an alkali earth metal atom, or a rare earth metal atom; Q represents a moiety of an inorganic acid or an active hydrogen compound derived by eliminating a proton, wherein Q is a halogen atom different from the halogen atom in the organic starting material having the halogen atom bonded to the carbon atom having the four σ bonds; and a represents an integer of 1 to 3) in the presence of a compound represented by general formula (1)
(wherein Z- represents an anion derived by eliminating a proton from an inorganic acid or an active hydrogen compound; R2 is the same or different; R2 each independently represent a C1-C10 hydrocarbon group or two R2 on the same nitrogen atom may be bonded with each other to form a ring with the nitrogen atom).

MQa (2)
(其中M代表碱金属原子、碱土金属原子或稀土金属原子;Q代表由消除质子衍生的无机酸或活性氢化合物的基团,其中Q是不同于有机起始材料中卤素原子的卤素原子,该卤素原子与具有四个σ键的碳原子相结合;a表示1到3的整数),在通式(1)表示的化合物的存在下
(其中Z-代表由无机酸或活性氢化合物中消除质子衍生的阴离子;R2相同或不同;R2各自独立地表示C1-C10烃基,或者两个R2在同一氮原子上可能与彼此结合形成与氮原子的环)。
