The Synthesis Of 1,3-Difluoro-2-Methyl-4-Phenylbenzene From A One-Pot Reaction Of Difluorocarbene And 1-Phenyl-2-Methylcyclobutene, Ruth Felicitas Menger Jan 2016

The Synthesis Of 1,3-Difluoro-2-Methyl-4-Phenylbenzene From A One-Pot Reaction Of Difluorocarbene And 1-Phenyl-2-Methylcyclobutene, Ruth Felicitas Menger

Senior Honors Projects, 2010-current

Previous studies show that 1,2-disubstituted cyclobutenes can be used in reaction with difluorocarbene to produce 1,3-difluorobenzenes. A pathway to the synthesis of these types of compounds is of interest due to their presence in fluoroquinolone antibacterials, resins, and insecticides. The synthesis is unique because the fluorine atoms from the difluorocarbene are not adjacent to each other when the ring expands to a benzene ring. This study focuses on the reaction of difluorocarbene with 1-phenyl-2-methylcyclobutene, which was synthesized in one-pot in 4 steps starting from 1-phenyl-1-propyne and zirconocene dichloride.
