Synthesis, crystal structure and protonation of the asymmetric iron-only hydrogenase model [Fe-2(CO)(3)(mu-pdt){mu,eta(2)-Ph2PCH2CH2P(Ph) CH2CH2PPh2}] (pdt = SCH2CH2CH2S) Heating [Fe-2(CO)(6)(mu-pdt)] (pdt = SCH2CH2CH2S) and bis(2-diphenylphosphinoethyl) phenylphosphine (...
Lignin contributes up to 30% of lignocellulosic biomass by weight and provides an alternative renewable source of aromatic chemicals. However, it has not been exploited effectively due to its natural complexity and high stability. Therefore, continuous a
The new N-(arylsilyl)anilines 1–5 have been obtained by the reaction of aryl(halo)silanes with the corresponding anilines in the presence of the auxiliary base triethylamine. The benzene parts of the anilines have been chosen such that their fluoro, methyl, and methoxy substituents exert dif...
