Direct alkylation of N,N-dialkyl benzamides with methyl sulfides under transition metal-free conditions

Autor: Can-Can Bao, Hui-Zhen Du, Yan-Long Luo, Bing-Tao Guan

Publikováno v: Communications Chemistry, Vol 4, Iss 1, Pp 1-8 (2021)

Direct conversion of amides to ketones typically requires the use of transition metal catalysts or reactive organometallic reagents. Here the direct alkylation of benzamides with methyl sulfides using LDA as base provides access to thioalkoxyketones.

Benzylic aroylation of toluenes with unactivated tertiary benzamides promoted by directed ortho-lithiation

Autor: Bing-Tao Guan, Hui-Zhen Du, Yan-Long Luo, Can-Can Bao

Publikováno v: Science China Chemistry. 64:1349-1354

The deprotonative functionalization of toluenes, for their weak acidity, generally needs strong bases, thus leading to the requirement of harsh conditions and the generation of by-products. Direct nucleophilic acyl substitution reaction of amides wit

Tuning the Electrically Conductive Network of Grafted Nanoparticles in Polymer Nanocomposites by the Shear Field

Autor: Yan-Long Luo, Bin Li, Xianling Chen, Yangyang Gao, Liqun Zhang, Xiaohui Duan

Publikováno v: Chinese Journal of Polymer Science. 38:1426-1434

Controlling the formation of the conductive network in the polymer nanocomposites (PNCs) is very meaningful to enhance their electrical property. In this work, we investigated the effect of grafted nanoparticles (NPs) on the conductive probability of

Research on Brittle Fracture of X70/X80 Line Pipes with Big Wall Thickness at Low Temperature

Autor: Shi Li Li, Nan Lin, Hai Bin Zhang, Yan Long Luo, Jun Qiang Wang, Hai Tao Wang

Publikováno v: Key Engineering Materials. 795:3-8

Based on research of the low temperature fracture property of high grade steel pipe, it shows that X70, X80 steel pipe and X80 tee have high Charpy impact toughness. However, as the wall thickness increases, the shear area of DWTT decreases rapidly,

Alkyl lithium-catalyzed benzylic C-H bond addition of alkyl pyridines to α-alkenes

Autor: Bing-Tao Guan, Yan-Long Luo, Yu-Feng Liu

Publikováno v: Organicbiomolecular chemistry. 18(34)

Bronsted base catalyzed C–C bond formation reactions have been extensively utilized as reliable, efficient, and atom economical methods in organic synthesis. However, the electrophiles were mostly limited to polar ones such as imines, carbonyl comp
