what have we got here...
ortho-alkylation of phenol with a terminal olefin, using dirhenium decacarbonyl as the catalyst. oh, yeah, everyone's got rhenium carbonyls lying around the stock room
ok looks like a few non-terminal alkenes worked too
catechol and hydroquinone gave mixed mono- and di-alkylation
in _mesitylene_ as the solvent. didn't they at least TRY to use something else? again, I complain that in older _Organic Syntheses_ entries, they'd talk about how they tried to use more commonplace solvents but failed
