PROCESS TO MAKE HIGHLY SUBSTITUTED INDENES USING METAL SLAT CATALYSTS

摘要

The present invention is a process to make l-aryl-2-bromo substituted indenes and l-phenyl-2-bromo substituted indenes that can have different functional groups present around the indene ring and/or the aromatic and/or phenyl ring. The indenes are made using the corresponding 1,2- biaryl-gem-dibromocyclopropane and/or 1,2-biphenyl-gem-dibromocyclopropanes and/or 1-aryl- 2-phenyl-gem-dibromocyclopropanes using a metal salts, a solvent, low temperatures.
