One pot asymmetrical double allylations of sodium sulfide catalyzed by an iridium complex along with a combination of caesium fluoride and water in dichloromethane have been realized and the double allylation products with two C-S bond chiral centers were obtained in 67-99% yields with b/l 81/19-99/1, dr 85/15-99/1, and 96-99% ee.

An iridium‐catalyzed allylic substitution of sodium phenyl selenide with unsymmetrical allyl carbonates was accomplished, which produced the linear allyl phenyl selenides in 38%–74% yields. An asymmetric iridium‐catalyzed allylation of sodium phenyl selenide was presented as well.

In this paper, a kind of microcapsule containing phase change material of n-octadecane was successfully synthesized based on in situ polymerization where trimethylol melamine and hexamethylol melamine were shell materials. We used different emulsification time, reaction time and different treatment to improve the quality of the microcapsules. The microcapsule and coated fabric were characterized by the optical microscope, Scanning Electronic Microscope (SEM), laser diameter distribution machine and Differential Scanning Calorimeter (DSC). The optical microscope and SEM pictures showed that this microcapsule has good surface configuration. Particle size with laser diameter distribution machine displayed that grains of the microcapsule were distributed evenly. The DSC results revealed the phasechanging temperature and enthalpy of the microcapsule.

Construct Chiral C2-Symmetric Bis(1-Substituted--allyl)sulfane. -The highly regio-, diastereo-and enantioselective Ir-catalyzed double allylation of sodium sulfide hydrate with a variety of allyl methyl carbonates (I) is described. This is the first example that sodium sulfide is used as an inorganic nucleophile in transition-metal-catalyzed allylation substitutions. It is noteworthy, that the allylation reaction efficiently generates two C-S chiral centers in one pot. The power of this methodology is demonstrated by the synthesis of the dihydro-thiophene derivative (IV) by ring-closing metathesis. -(ZHENG, S.; HUANG, W.; GAO, N.; CUI, R.; ZHANG, M.; ZHAO*, X.; Chem.
