Reaction of 2 molar amount of 2-(trimethylsilyl)phenyl triflate with thiiranes and aldehydes in the presence of CsF afforded vinyloxiranes in one-pot operation. Reaction of benzyne with thiiranes gave the corresponding alkenyl phenyl sulfides, which further reacted with another molar of benzyne to afford sulfonium ylide intermediates. Further treatment of aldehydes gave the corresponding vinyloxiranes.
