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).

2,4,6-Trichlorophenol (TCP) sulfonate esters undergo effective aminolysis under conventional heating and microwave irradiation; the reactivity of these species is such that chemoselective transformations of PFP sulfonate esters can be achieved.
A process for the preparation of ketones corresponding to the general Formula I
1
in which &bgr;,&ggr;,&dgr;-allenic, di-unsaturated ketones and/or &agr;,&bgr;,&ggr;,&dgr;-conjugated, di-unsaturated ketones, obtained by reaction of propargyl alcohols with enol ethers and are converted in direct manner by hydrogenation to the saturated ketones corresponding to the general Formula I without purification by distillation.
Catalytic compositions and catalytic processes are provided. The catalytic compositions are produced by the process that comprises contacting an organonickel compound with a cyclicazacarbyl compound. Optionally, one or more catalytic promoters can be present in the catalytic compositions. Additionally, one or more olefins can be contacted with one or more of these catalytic compositions to form oligomerization products and/or polymerization products.
