Intramolecular transfer of sulfonyl oxygen to vinylcarbene generated in the reaction of tris(isopropylthio)cyclopropenyl cation with arylsulfinate salts
Tris(isopropylthio)cyclopropenylium perchlorate 1 reacts with sodium arylsulfinates 2a–d in dry acetonitrile and benzene under reflux to give arylsulfinylpropenethioates 3a–d, accompanied by the formation of arylsulfonylallenes 4a–d, through cyclopropene intermediates 5a–d and then vinylcarbenes 6a–d.
The reaction of tris(isopropylthio)cyclopropenyliumperchlorate (1) with α-lithiated tosylmethyl, benzyl and benzoylmethyl isocyanides 2a-c in dry tetrahydrofuran gave the pyridine derivatives 3a-c respectively.
