Y. Kita et al., PREPARATION OF BIS(ARYLTHIO)IODOBENZENE AND REACTION WITH 1-ALKYNES -A NOVEL ROUTE TO 1,2-BIS(ARYLTHIO)ALKENES, Tetrahedron letters, 35(17), 1994, pp. 2717-2720
The in situ reaction of a novel hypervalent iodine reagent 2b having a
n arylthio ligand, prepared from phenyliodine diacetate and 2,3,5,6-te
trafluorothiophenol 1b in pyridine, with 1-alkynes 3 gave 1,2-bis(aryl
thio)alkenes 4 in good yields.
