- POLYCARBONATE RESIN COMPOSITION, MOLDED ARTICLE, POLYCARBONATE RESIN, AND END-CAPPING AGENT FOR POLYCARBONATE RESIN
-
A polycarbonate resin composition, a molded article, a polycarbonate resin, and an end-capping agent for polycarbonate resins are provided. The polycarbonate resin composition contains: a polycarbonate resin having a terminal structure represented by Formula (A) and having a viscosity average molecular weight from 1×104 to 5×104, and a stabilizer. In Formula (A), R1 is selected from the group consisting of a hydrogen atom, halogen atoms, linear alkyl groups having from 1 to 9 carbons, branched alkyl groups having from 3 to 9 carbons, linear alkenyl groups having from 2 to 9 carbons, branched alkenyl groups having from 3 to 9 carbons, and aryl groups having from 6 to 12 carbons; and R2 to R7 are each independently selected from the group consisting of a hydrogen atom, alkyl groups having from 1 to 9 carbons, and alkoxy groups having from 1 to 9 carbons.

- Copper-Catalyzed Acetylation of Electron-Rich Phenols and Anilines
-
An approach has been developed for the copper-catalyzed acetylation of phenols and anilines with potassium thioacetate as an acetylating reagent. Although only electron-rich phenols and anilines are compatible with this protocol, the reaction can provide moderate to high yields under mild conditions. Compared with other acetylating reagents, the current reagent has certain advantages, such as its low cost, easy availability, stability, insensitivity to water or air, and ease of storage.

- POLYMERIZABLE COMPOUND AND OPTICAL ANISOTROPIC MATERIAL
-
PROBLEM TO BE SOLVED: To provide a polymerizable compound which has high storage stability without inducing crystallization or the like when added to a polymerizable composition, to provide a polymerizable composition containing the polymerizable compound, which gives little haze or unevenness when a polymer is produced by polymerizing the polymerizable composition, and which hardly causes reduction in retardation when the polymer is heat treated, and further, to provide a polymer obtained by polymerizing the polymerizable composition, and an optical anisotropic material using the polymer. SOLUTION: A compound expressed by general formula (I) is provided; and also provided are a composition containing the above compound, a polymer obtained by polymerizing the composition, and an optical anisotropic material using the polymer.

- The first vinyl acetate mediated organocatalytic transesterification of phenols: A step towards sustainability
-
The present report outlines our efforts toward a simple yet elegant protocol for O-acylation of a wide variety of phenols. This highly enabling and solventless method relies on vinyl acetate as an innocuous acyl donor and DABCO as an organocatalyst. Operational simplicity, excellent yields, higher and faster conversion rates without excess reagents, a simple workup and essentially no need of columns are some of the salient features of the reported protocol.
