Duhamel, Thomas published the artcileCooperative iodine and photoredox catalysis for direct oxidative lactonization of carboxylic acids, Quality Control of 1949-41-3, the publication is Chemical Communications (Cambridge, United Kingdom) (2019), 55(7), 933-936, database is CAplus and MEDLINE.
A new method for the formation of ¦Ã- and ¦Ä-lactones from carboxylic acids through direct conversion of benzylic C-H to C-O bonds was described. The reaction was conveniently induced by visible light and relied on a mild cooperative catalysis by the combination of mol. iodine and an organic dye.
Chemical Communications (Cambridge, United Kingdom) published new progress about 1949-41-3. 1949-41-3 belongs to catalysis-chemistry, auxiliary class Carboxylic acid,Benzene, name is 2-Methyl-4-phenylbutanoic acid, and the molecular formula is C11H14O2, Quality Control of 1949-41-3.
