Electrophilic Nitration of Electron-Rich Acetophenones
摘要:
It is demonstrated that electron-rich disubstituted acetophenones react according to various electrophilic nitration conditions that generally lead to ipso substitution accompanying the conventional reaction. The hydroxy substituent does not seem prone to favor such behaviour.

A process for the conversion of lignocellulosic biomass to hydrocarbons is provided. The biomass is subjected to aqueous phase partial oxidation (APPO) in the presence of a heterogeneous oxidation catalyst to selectively provide one or more carboxylic acids in good yields. The carboxylic acids are further upgraded to hydrocarbons in the presence of one or more catalysts, which are capable of catalyzing a ketonization reaction, an aldol condensation reaction, a hydrodeoxygenation reaction, or combinations thereof, and then separating out the hydrocarbons from the one or more catalysts.

Mor(DalPhos) for Me(sylates): Described are the first examples of ketone mono‐α‐arylation and primary aliphatic aminemonoarylation employing aryl methanesulfonate coupling partners. A range of functionalized arylmesylates were employed with dialkyl ketones, and also with primary and secondary amines as well as the otherwise challenging coupling partners acetone and methylamine.

It is demonstrated that electron-rich disubstituted acetophenones react according to various electrophilic nitration conditions that generally lead to ipso substitution accompanying the conventional reaction. The hydroxy substituent does not seem prone to favor such behaviour.
