Ni-Catalyzed enantioselective reductive arylcyanation/cyclization of: N -(2-iodo-aryl) acrylamide

A Ni/(S,S)-BDPP-catalyzed intramolecular Heck cyclization of N-(2-iodo-aryl) acrylamide with 2-methyl-2-phenylmalononitrile was developed to give oxindoles with good enantioselectivities. We found that utilizing such an electrophilic cyanation reagent cou

Method for synthesizing methacrylic acid by decarboxylating itaconic acid

The invention relates to a method for synthesizing methacrylic acid by decarboxylating itaconic acid. The method comprises the following steps: adding water, itaconic acid and a catalyst into a high-pressure kettle, sealing the high-pressure kettle, introducing nitrogen, and conducting reacting at 190-260 DEG C for 1-8 hours to obtain methacrylic acid, wherein the catalyst is a modified hydroxyapatite catalyst with a general formula of M10(ZO4)6(X) 2, M is one or two selected from a group consisting of Ca, Mg, Ba, Fe or Sr, ZO4 is PO4, and X is OH. The modified hydroxyapatite catalyst has the advantages of being high in activity and selectivity, easy to separate, environmentally friendly and the like, an itaconic acid conversion rate is larger than 98%, and the selectivity of the target product methacrylic acid can reach 75% or above at most.

High-performance 3D printing UV-curable resins derived from soybean oil and gallic acid

Developing sustainable 3D printing materials has attained intensive interest due to the rapid growth of the 3D printing industry and the concerns on depletion of fossil resources and environmental pollution. In this work, a novel biobased UV-curable oligomer (GMAESO) was firstly synthesized from epoxidized soybean oil (ESO) and gallic acid (GA) via a 'green' one pot method. The obtained biobased oligomer possessed a biobased content of 82.9%. By co-photopolymerization of the obtained oligomer with a hydroxyethyl methacrylate (HEMA) diluent, a series of UV-curable materials were prepared, and their properties as well as curing behaviors were investigated. Notably, the resulting GMAESO resins with high HEMA contents (50-60%) showed low viscosities (52-93 mPa s) and excellent thermal and mechanical properties (a Tg of 128-130 °C, Tp >430 °C, a tensile strength of 42.2-44.4 MPa, etc.) which were comparable or superior to a commercial product. Furthermore, the optimal resin (GMAESO with 50% HEMA) was used for digital light processing (DLP) 3D printing. The resin showed lower penetration depth (0.277 mm) than the commercial resin, thus different-structured objects with high resolution were successfully printed. In general, the developed bio-based UV-curable resins are very promising for application in the 3D printing industry.
