An unusual and unexpected synthesis of 3-(2-(arylamino)thiazol-4-yl)-2H-chromen-2-ones was observed by the reaction of Et 2-(chloromethyl)-2-hydroxy-2H-chromene-3-carboxylate with various arylthioureas in ethanol under mild reaction conditions with excellent yields. The ambiguity in the structure of the obtained products was solved by recording its single-crystal X-ray anal. This protocol was found to be a novel approach for the preparation of title compounds via benzopyran ring opening. A systematic plausible mechanism was proposed for the formation of the product. Also, an efficient one-pot three-component method was demonstrated for the formation of title compounds starting from salicylaldehyde.

PhS- and PhNH-functionalized dienes are copolymerized efficiently with butadiene to stereoregular copolymers by [(mesitylene)Ni(allyl)][BAr^F₄] (Ni-1). Overall polymerization rates and comonomer incorporations depend strongly on the linker length between the diene moiety and functional group, in, e.g., PhS-(CH₂)_xC(=CH₂)-CH=CH₂ (PhS-x-BD, x = 3-7), in particular for certain linker lengths high comonomer reactivity ratios stand out. This effect is related to a favorable binding of the comonomer to the active site comprising coordination of its functional group, which significantly enhances comonomer incorporation in the growing polymer chain.
