desired branched alkane products. Besides costly Pt electrodes also (RuxTi1−x)O2 on Ti electrodes exhibited a notable activity for cross-Kolbe electrolysis. As some of the products are insoluble in water, easy product isolation and reuse of the reaction solvent is enabled via phase separation. Several side products have been identified to evaluate the efficiency of the reaction and to elucidate the factors
生物衍生酸的直接电催化转化代表了一种从木质纤维素生物质生产增值化学品和定制燃料的有前途的技术。在目前的贡献中,我们报道了琥珀酸乙酯氢,甲基琥珀酸氢甲酯和甲基己酸与异戊酸的电化学脱羧和交叉偶联。遵循绿色化学原理,在环境温度下于水溶液或甲醇中进行反应。已经获得了起始原料的高转化率,其向期望的支链烷烃产物的最大收率在42%至61%之间。除昂贵的Pt电极外(Ru x Ti 1- x)O 2Ti电极上的Sb表现出了显着的跨Kolbe电解活性。由于某些产物不溶于水,因此可通过相分离轻松分离产物并重新使用反应溶剂。已经鉴定了几种副产物以评估反应的效率并阐明影响产物选择性的因素。对所产生的烷烃和酯作为内燃机燃料的潜力进行了评估。虽然较长的烷烃是压燃式发动机的有希望的候选者,但较小的酯则是火花点火式发动机的一个有趣的选择。

A heterocyclic compound or a salt thereof represented by the formula (1):
where R
2
represents a hydrogen atom or a lower alkyl group;
A represents a lower alkylene group or lower alkenylene group; and
R
1
represents an aromatic group or a heterocyclic group. The compound of the present invention has a wide treatment spectrum for mental disorders including central nervous system disorders, no side effects and high safety.
Provided are triazole derivatives of Formula I which are potent inhibitors of spleen tyrosine kinase and pharmaceutical composition. The triazole derivatives are useful in the treatment and prevention of diseases mediated by said enzyme, such as asthma, COPD, rheumatoid arthritis, and cancer.
