Inexpensive and bench stable diarylmethylium tetrafluoroborates as organocatalysts in the light mediated hydrosulfonylation of unactivated alkenes

Can a cheap and bench stable salt catalyse the hydrosulfonylation of unactivated alkenes? Yes it does! Just mix a diarylmethylium tetrafluoroborate salt with a sulfinate salt, wait for the formation of the adduct and turn purple light on it.
