A mild and metal-free procedure is reported for the aerobic oxidation of substituted toluenes to carboxylic acids by using CBr 4 as initiator under irradiation from a 400 nm blue light-emitting diode.
METHOD FOR PRODUCING 2-HALOGENATED BENZOIC ACIDS
-
Paragraph 0064, (2018/04/20)
The purpose of the present invention is to provide a method for producing 2-halogenated benzoic acids, the method imparting high regioselectivity (high selectivity) and having a shorter reaction time than does the conventional reaction. This method for producing 2-halogenated benzoic acids, in order to achieve the above purpose, is characterized in that benzoic acids and a halogenating agent are reacted in the presence of an alkaline compound, making it possible to highly selectively obtain 2-halogenated benzoic acids.

A series of electronically modified second-generation cis-dichloro ruthenium ester chelating benzylidene complexes was prepared, characterized, and benchmarked in a typical ring-opening metathesis polymerization (ROMP) experiment. The electronic tuning of the parent chelating benzylidene ligand (2-ethyl ester benzylidene) was achieved by substitution at the 4- and 5-positions with electron-withdrawing nitro or electron-donating methoxy groups. The effect of the electronic tuning on the cis-trans isomerization process was studied experimentally and theoretically. Density functional theory calculations clearly revealed the influence of electronic modification on the relative stability between the cis and trans isomers, which is decisive for the activity of the studied compounds as initiators in ROMP.
