Electrophilic and Nucleophilic Substitutions of 2-Amino- and 2-Hydroxy-1,3-diazaazulenes

2-Amino (2) and 2-hydroxy-1,3-diazaazulenes (3) underwent smoothly electrophilic bromination under basic conditions to give 2-amino-4,6,8-tribromo- (4) and 6-bromo-2-hydroxy-1,3-diazaazulenes (7), respectively.Bromo derivatives 4 and 7 underwent some nucleophilic substitutions, e.g., 4 reacted with ease with sodium methoxide to give 2-amino-4,6,8-trimethoxy-1,3-diazaazulene (10).

Direct C–H Carboxylation Forming Polyfunctionalized Aromatic Carboxylic Acids by Combined Br?nsted Bases

CO2 fixation into electron-deficient aromatic C–H bonds proceeds with the combined Br?nsted bases LiO-t-Bu and LiO-t-Am/CsF/18-crown-6 (t-Am = CEtMe2) under a CO2 atmosphere to afford a variety of polyfunctionalized aromat

Sterically Hindered Carboxylic Acid Esters

Methods have been developed for preparation of esters formed by sterically hindered benzoic acids and various alcohols, which were difficult to obtain previously. The methods are based on the reaction of carbenium ions, generated from primary aliphatic N-nitroamines by the action of nitrous acid or Lewis acids, with carboxylic acid at the sterically accessible oxygen atom of the carboxy group. Reactions of nitrobenzoic acids and benzenepolycarboxylic acids with 2,2,2-trinitroethyl hydrogen sulfate provide an effective method for preparation of corresponding trinitroethyl esters.
