Vinyl-containing organosilicon compounds as the Speier catalyst additives

Тонкие химические технологии, 2008
The effect of a number of vinyl-containing organosilicon compounds used as the Speier catalyst additives upon the activity of the resulting catalyst was studied. The most active additives turned out to be hexavinyldisiloxane, tetramethyldivinyldisiloxane,

The concept of Gallium-controlled double C–H functionalization of aliphatic CH2-groups driven by Vinyl carbocations

Nature Communications
The direct C–H activation of inert C(sp3)–H bonds in a hydrocarbon chain has been a very attractive target in organic synthesis for many decades. Among all the variety of processes, those driven by vinyl carbocations are quite scarce thus far, and it is ...

PDMS Membrane Using Phenyl as Rigid Molecular Spacer for Phenol Recovery

Engineering in Life Sciences
Polydimethylsiloxane (PDMS) is extensively utilized for the recovery of bio‐alcohols, but it encounters significant obstacles in volatile organic compounds (VOCs) removal, because of the narrow size for molecules diffusion.
