with an aqueous phase soluble (PTA)4RuCl2 precatalyst, for reductions (sodium formate) of aromatic and aliphatic aldehydes (biphasic reaction conditions) also showed no apparent steric or electronic effects, including other data on inhibition by CO of the reduction reaction, which to our thinking,...
The syntheses of two new derivatives of 4 - pyrone, by the reaction of adipyl choloride with enamines deriving from chainketonesand aldehydes, are described. 本文由链状酮的烯胺与己二酰氯反应合成两个新的4-吡喃酮衍生物。 The invention is applied to the catalytic reactions such as aromaticketone...
Ketones, aldehydes, and alcohols predominately are produced from petroleum and natural gas. Because fossil fuels are a finite resource, it is desirable to identify processes that use renewable resources, such as biomass. Biomass-based alcohol production is currently practiced using corn as feedstock;...
(1). This reagent was featured in our first disclosure on the chemistry of enoxytrichlorosilanes, 7 and although susceptible to chiral Lewis base catalysis, 8 its hyper- reactivity toward aldehydes led to only modest enantioselectivities. Moreover, the strong chelation of the trichlorosilyl ...
