| Research Abstract |
Tris (isopropylthio) cyclopropenylium perchlorate (1) is a useful three-carbon building block in organic synthesis. The results our obtained are summarized below.
1) Tris (isopropyltho) cyclopropenylium perchlorate (1) reacts with potassium dithiocarbamates to give thiophene derivatives in good yield.
2) Tris (isopropylthio) cyclopropenylium perchlorate (1) reacts with sodium arylsulfinates in dry acetonitlile and benzene under reflux to give arylsulfinylpropenethioates in good yield.
accompanied by the formation of arylsulfonylallenes, through cyclopropene intermediates and then vinylcarbene,
3) The reaction of tris (isopropylthio) cyclopropenylium perchlorate (1) with alpha-Lithiated tosylmethyl, benzyl and benzoylmethyl isocyanides in dry tetrahydrofuran gave the pyridine deribatives, respectively.
