Fluoroboron compound, aminomethylating agent for aromatic ring made of the same, and production method of compound containing aminomethyl aromatic ring using aminomethylating agent

摘要

A production method of a compound containing a primary, secondary, or tertiary aminomethyl aromatic ring of the present invention includes: using a fluoroboron compound or a dimer thereof, or solvates thereof, which are represented by a formula (I):Ra(Rb)N—CH₂—BF₃M  (I)as an aminomethylating agent for an aromatic ring; and reacting the aminomethylating agent with an aromatic ring-containing compound, which can react with the aminomethylating agent, under the presence of a metal catalyst such as a palladium compound so as to perform the direct aminomethylation of the aromatic ring.
