Modern pentafluorosulfanyl (SF5) chemistry has an Achilles heel: synthetic accessibility. Herein, we present the first approach to aryl-SF4Cl compounds (key intermediates in state-of-the-art aryl-SF5 synthesis) that overco

Thermolysis and photolysis of 1,2,3-benzothiadiazole 10c furnish the products 11c - 15c. 13C-labelling experiments demonstrate that an intermediate benzothiirene 1c is not formed.Isotopomeric reaction products are due to H-shifts.Electron withdrawing ester groups in 6-position enable the ring closure to the substituted benzothiirenes 1d, e on the photochemical but not on the thermal route.A proof is given by an extensive study of the disulfides 14d, e, 14d', e', and 14d'', e'', generated in the thermolysis, photolysis and by an independent procedure.The results are based on 13C and 1H NMR measurements.Unequivocal signal correlations were made by deuterations and heteronuclear double resonances.
