A first object of the present invention is to provide a method for producing a carboxyl group-containing water-soluble polymer capable of giving neutralized viscous solutions excellent in thickening effect even when the aqueous solutions of the carboxyl group-containing water-soluble polymer have a low concentration. A second object of the invention is to provide a method for producing a carboxyl group-containing water-soluble polymer capable of giving neutralized viscous solutions excellent in thickening effect at low concentration levels and, at the same time, capable of being dispersed and dissolved in water at high concentrations with ease.
The prevent invention is a method for producing a carboxyl group-containing water-soluble polymer by reacting an α,β-unsaturated carboxylic acid and a compound having two or more ethylenically unsaturated groups in the presence of a radical polymerization initiator, which method is characterized in that the reaction is carried out in the presence of a (meth)acrylic acid derivative represented by the general formula (1):
(in the formula, R
1
and R
2
each independently represents a hydrogen atom or a methyl group and n represents 1 or 2).

In the presence of LiBr, a palladium/copper combination catalyzes dehydrogenative amidobrominations of acrylates with NH‐sulfoximines, leading to N‐vinylated products by dual NH/CH coupling, followed by oxidative enamide bromination. Mechanistically, the dominoprocess is proposed to involve palladium(II) species as key intermediates. First synthetic applications of the products have been demonstrated
