A tandem synthesis
for structurally novel 3-chloro-4-iodoisoxazoles
was developed by simply mixing 1-copper(I) alkynes, dichloroformaldoxime,
and molecular iodine together. The combination of 1-copper(I) alkyne
and molecular iodine was well used as a synthetic equivalent of 1-iodoalkyne
without the need for tedious preparation, purification, and storage
of 1-iodoalkyne.
