The cover picture shows an impression of industrial preparation of aromatized Nimodipine by sunlight and air on the arid lands. Visible light is most strongly emitted in the solar spectrum on the surface of the earth. Now Qiang Liu and co-workers develop a metal-free and visible-light driven aerobic aromatization catalyzed by organic dye eosin Y bis(tetrabutyl ammonium salt) (TBA-eosinY). With the aid of K2CO3, the aerobic catalytic system converts 1,4-dihydropyridines such as Nimodipine to their corresponding pyridine derivatives efficiently under visible light irradiation at room temperature. More details are discussed in the article by Liu et al. on page 1245–1250.

- Towards Reaction Control: An Expeditious Access to Racemic 5-Substituted Tetramates and 5-Substituted Tetramic Acids from Malimides
Pei-Qiang Huang, Wei Ou and Jian-Liang Ye

A versatile and divergent two-step transformation of malimides to racemic tetramates and tetramic acids is described. The method consists of Grignard reagent addition with malimides, and concentrated HCl-promoted chemoselective transformations of the latter.
- Thermal and pH Dual Responsive Copolymer and Silver Nanoparticle Composite for Catalytic Application

Thermal and pH dual responsive P(NIPAM-co-VI) copolymer was used as carriers to load Ag nanoparticles for the first time. The nanoparticles could be stably dispersed at all pH values, and were favorable to be used as a catalyst at a wide pH range, but more efficient at low pH.
