Under the conditions of oxidative gold catalysis, exposure of ethylene to aryl silanes and alcohols generates products of 1,2-oxyarylation. This provides a rare example of a process that allows catalytic differential 1,2-difunctionalization of this feedstock chemical.

supporting information, p. 1701 - 1704 (2017/11/23)
A practical oxidative homocoupling reaction of aryltri-methylsilanes has been achieved by Pd/o-chloranil catalytic system. The reaction shows the good functional group tolerability toward bromo, fluoro, ester, and methoxy groups to give a series of biaryls bearing electron-withdrawing and -donating groups. The boronate group is also retained on biaryls without any ArB bond cleavage, which is highly advantageous for orthogonal coupling.

A series of silylated triarylphosphines was synthesized. Hydrosilylation reactions of styrene with triethoxysilane catalyzed by RhCl3/silylated triarylphosphine complexes were investigated. The complexes RhCl3/phenylbis(4-trimethylsilylphenyl)phosphine and RhCl3/tris(4-trimethylsilylphenyl)phosphine exhibited higher activity as well as greater β-adduct selectivity, and no unsaturated product was obtained. The results suggest that the silyl moieties have a significant impact on the catalytic process. Copyright

The activity of cis-cinnamic acid (cis-CA), one of the allelochemicals, in plants is very similar to that of indole-3-acetic acid (IAA), a natural auxin, and thus cis-CA has long been believed to be an analog of auxin. We have reported some structure-acti
Tetrahedral silicon-based luminescent molecules: Synthesis and comparison of thermal and photophysical properties by various effect factors

A series of luminescent molecules were presented employing the tetrahedral structural motif of the silicon atom, which further connected different N-containing heterocycle functional groups in their periphery using phenyl rings as the bridges. These compounds included three kinds of N-heterocycle functional silanes: imidazole derivatives (1a-h), pyrazole derivatives (2a-e) and benzimidazole derivatives (3a-b), and their structures were fully characterized by FT-IR, 1H NMR, 13C NMR and HRMS. The TGA results indicate that they all exhibit high thermal stabilities. The photophysical properties demonstrate that they are fluorescent in the violet-blue region and could be potentially applied as blue emitters for organic light-emitting diodes (OLEDs). The effect factors of sort, disposition and number of substituent groups and N-containing heterocycle functional groups on their thermal and photophysical properties were investigated. Molecular calculations were also performed to support the experimental results. Moreover, the computational results reveal that these compounds all exhibit relatively large HOMO-LUMO band gaps with the range from 4.82 eV (2d) to 5.19 eV (1a and 2c), making them become promising candidates as host materials for emitters and hole/electron blocking materials in OLEDs display.
