Silica Chloride (SiO<sub>2</sub>-Cl), a New Heterogeneous Reagent, for the Selective and Efficient Conversion of Benzylic Alcohols to Their Corresponding Chlorides and Iodides
Abstract Structurally different benzylic alcohols were efficiently converted to their corresponding chlorides by silica chloride (SiO2-Cl) in CHCl3 at room temperature. Silica chloride is also able to convert benzylic alcohols to their iodides in the presence of NaI in a mixture of CH3CN/CHCl3 in excellent yields.
摘要 在室温下,在 CHCl3 中的氯化硅 (SiO2-Cl) 可以将结构不同的苄醇有效地转化为其相应的氯化物。在 NaI 存在下,在 CH3CN/CHCl3 混合物中,氯化硅也能够以极好的收率将苄醇转化为其碘化物。

Prevention or therapy of inflammatory diseases caused by invasion of leukocytes such as monocytes, lymphocytes and eosinophils, by providing a substance which inhibits cell adhesion via an adhesion molecule, especially adhesion molecule VLA-4, is disclosed. A group of carboxylic acid derivatives represented by, for example,
and adhesion molecule inhibitors comprising the same as an effective ingredient were provided.

A new type of chemistry of carbon disulfide proceeding by way of nucleophilic attack of tris(trimethylsilyl)methyllithium (TsiLi) at carbon of carbon disulfide is reported. The treatment of TsiLi and CS2 with some symmetrical and unsymmetrical benzyl halides has yielded novelmultifunctionalcompounds with SiMe3, SH and CS groups. The obtained compounds (mercapto-silyl-thiones) have been produced with

supporting a bis-imidazolium iodide salt with xylene or octane as a linker between the imidazolium units were identified as the most activecatalysts and displayed high turnover numbers and improved productivity compared to known supported ionicliquidcatalysts. The most promising mlc-SILP catalysts were further studied to tune the reaction conditions towards optimum catalytic performance and to investigate
