1,2-Benzisothiazol-3(2H)-one (BIT) is one of the most common chemical biocides in industrial products, with a heterocyclic structure and a wide range of antimicrobialactivity. A library of BIT derivatives was synthesized and characterized, from which 18 compounds were selected, tested for anti-bacterial activity relative to the parent molecule and amenable of coupling to plant polysaccharides in general
An efficient copper-catalyzed reaction for the synthesis of benzisothiazol-3(2H)-ones has been developed, starting from easily available 2-halobenzamides and carbondisulfide, which gave the corresponding target products in 30–89% yield for 25 examples. The reaction proceeds via a consecutive process with S–C bond and S–N bond formation.

Provided is a heat-shielding material including a substrate; a metal particle-containing layer which contains flat metal particles with a hexagonal shape or a circular shape; and a low refractive index layer with a refractive index of 1.45 or less, in which flat metal particles in which a principle planar surface of the flat metal particles is set with a planar orientation in a range of 0° to ±30° on average with respect to the other surface of the metal particle-containing layer are 50% by number or more of all the flat metal particles, the low refractive index layer is arranged on an uppermost surface on an indoor side when installing the heat-shielding material on a window glass, and the heat-shielding performance, visible light transmittance, and lightfastness in the heat-shielding material are excellent; and a window glass.
