I stumbled across this similar reaction at OrgSyn. Again it involves Pd-catalysed nucleophilic aromatic substitution on an aryl triflate, this time by an alkylthiol. The substitution even works when there is an electron donating group para to the -OTf leaving group (and it's microwave free
).

It'd be great if it could be applied to more heavily substituted aromatics; and if it worked on halides, it'd be an excellent one-step from 2C-X to 2C-T-anything you can think of. It could also be a nice way to 3,1-benzoxathiole-6-yl carboxaldehyde - the 4-thio analogue of piperonal, via the triflate ester of vanillin, followed by dealkylation and methylenation.
