Interrupted CarbonylâAlkyne Metathesis
Carbonylâolefin metathesis and carbonylâalkyne metathesis represent established reactivity modes between carbonyls, alkenes, and alkynes under Lewis and BrĂžnsted acid catalysis. Recently, an interrupted carbonylâolefin metathesis reaction has been reported that results in tetrahydrofluorenes via a distinct fragmentation of the reactive intermediate. We herein report the development of an analogous transformation interrupting the carbonylâalkyne metathesis reaction path resulting in dihydrofluorene products relying on Lewis acidic superelectrophiles as active catalytic species.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153682/1/adsc201901358.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153682/2/adsc201901358_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153682/3/adsc201901358-sup-0001-misc_information.pd
