摘要:
3-[2-(N-p-Toluenesulfonyl)aminophenylthio]prop-1-yne, reacted with aryl iodides in the presence of Et3N in THF solution with (PPh3)(2)PdCl2 (3 mol%) and CuI (40 mol%) at room temperature for 8 h followed by reflux for 20 h to yield diaryl sulfides by a depropargylation and S-arylation reaction.

Oxygentransfersfromnitrogroup to both the sulfur and acetylenic triple bond are noticed in parallel fragmentation pathways during the electronimpact induced decompositions of 3-(o-nitrophenylthio)-1-propynes. Single oxygentransferfromnitrogroup to sulfur leads to abundant ions corresponding to o-nitrosobenzenesulfinyl cation and [M–SO]+· while a concerted doubleoxygentransfer to sulfur followed
