Object To provide a method for producing a bis-quaternary ammonium salt efficiently and a novel synthetic intermediate thereof.
Solution The present invention relates to a method for producing a bis-quaternary ammonium salt represented by a general formula [3] which comprises reacting a disulfonic acid ester represented by a general formula [1] (in the formula, definitions of two R
1
's and T are as described in claim
1
) with a tertiary amine represented by a general formula [2] (in the formula, definitions of R
3
to R
5
are as described in claim
1
), and a disulfonic acid ester represented by a general formula [1′] (in the formula, two R
16
's represent independently a halogen atom or a C1-C3 fluoroalkyl group, and two m's represent independently an integer of 1 to 5).

Pd-Catalyzed Alkylation of (Iso)quinolines and Arenes: 2-Acylpyridine Compounds as Alkylation Reagents
The first Pd-catalyzed alkylation of (iso)quinolines and arenes is reported. The readily available and bench-stable 2-acylpyridine compounds were used as an alkylation reagent to form the structurally versatile alkylated (iso)quinolines and arenes. The method affords a convenient pathway for the introduction of alkyl groups into organic molecules.
