A novel Cu(0)-Cu(I)-mediated Caryl-Caryl Ullmann coupling has been successfully developed. The use of Cu(I) salts allowed the reactions to proceed under relatively mild conditions (65 °C in DMSO for 15–72 h). The developed method was compatible with a relatively wide range of functional groups simultaneously present on the aromatic ring of different electronic nature. The aryl halides with an electron-withdrawing

The conformational preference of 2,2′-bisanilides was investigated by variable-temperature NMR spectroscopy, NMR titration and diffusion experiments, IR spectroscopy, computational analysis, and X-ray crystallography. The formation of a conformation having the two amide moieties linked by an intramolecular hydrogen bond was detected at low temperatures. The interconversion kinetics of the two conformational
The present invention relates to compounds of the formula
where R1, R2 and R3 are independently selected from alkoxy radicals having from 1 to 8 carbon atoms, x is O or an integer of from 1 to 10; and Y is Li, K or Na. These compounds may be used as silica couplers in rubber compositions.
Suggested is a carbon black composition showing a narrow Aggregate Size Distribution (ASD) characterized by a ΔD50/Dmode value of 0,58 to 0,65 and a Relative Span (D90-D10)/D50 of about 0,5 to about 0,8, which is obtainable by means of a modified furnace reactor. The composition shows superior additive performance and allows producing e.g. bus or truck tires with improved wear resistance and reinforcement.
