was found to be a good pre-catalyst
for aldoxime dehydrations in open air. Compared with the previously
reported (PhSe)2-H2O2 system, it
is more stable and milder, affording broader application scopes due
to a higher functional group tolerance. The control experiments for
mechanism study disclosed that air was the key factor for the reaction
to maintain enough concentration of PhSeOH, which should be the real
catalytic species.
