We
report
an
electrophotocatalytic
process
that
enables
the
thiocyanation
and
sulfonylation/cyclization
of
alkenes.
It
is
applicable
to
a
wide
range
unactivated
alkenes,
using
inexpensive
photocatalyst
2,4,6-triphenylpyrylium
tetrafluoroborate
(TPPT)
produce
diverse
array
heterocycles
containing
sulfonyl
thiocyano
groups
with
good
functional
group
tolerance.
The
protocol
operates
under
mild,
chemical
oxidant-
transition-metal-free,
broad

substrates.
Preliminary
mechanistic
studies
suggest
reaction
involves
combination
electrolysis
reductive
quenching
photocatalytic
