cleavage catalyzed by transition metal, through which alkyl sulfonates could undergo an intramolecular desulfitative C–O coupling to form aryl alkyl ethers in the presence of a nickel catalyst. Meanwhile, aryl sulfonates perform similarly to give diarylethers catalyzed by a palladium complex. This transformation could tolerate a wide range of functionalities. Controlled experiments reveal that the 2-pyridyl
The present invention relates to polymerisable compounds, to processes and intermediates for the preparation thereof, and to the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays, especially in LC displays of the PS (polymer stabilised) or PSA (polymer sustained alignment) type.
Methods are disclosed for sterilizing tissue to reduce the level of one or more active biological contaminants or pathogens therein, such as viruses, bacteria, (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria, chlamydia, rickettsias), yeasts, molds, fungi, prions or similar agents responsible, alone or in combination, for TSEs and/or single or multicellular parasites. The methods involve sterilizing one or more tissues with irradiation.
The invention relates to a preparation having light-protection properties comprising at least one compound of the formula I
