N-Substituted isothiazol-3(2H)-ones can be easily prepared fromN-substituted 3-benzoylpropi-onamides in two experimentally simple steps, in satisfactory overall yields. Reaction of the amides with excess thionylchloride results in the formation of N-substituted 5-benzoylisothiazol-3(2H)-ones, which are readily debenzoylated with alkali to the corresponding N-substituted isothiazol-3(2H)-ones. This

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.
Synthesis and antibacterial activity of 2-(4-substituted phenyl)-3(2H)-isothiazolones
the reference drugs some compounds showed comparable or higher activities. In contrast to results of the previous studies, some 5-chloro derivatives showed lower or comparable activities against some tested microorganism, in comparison with analogues without C-5 substitution. In general, most of the compounds bearing electron withdrawing group at 4-position of the phenyl ring were more active against
