Abstract

Addition of 1,5-dithiacyclooctane (1,5-DTCO) to CaY resulted in electron transfer formation of the corresponding radical cation, which was characterized by EPR and diffuse reflectance UV–VIS spectrometry and which undergoes an unprecedented reaction with molecular oxygen to give mono- and bis-sulfoxide products.

  13. CaY was prepared by stirring NaY (5 g) at 90 °C for 5 h with 20 ml of a 0.5 M aqueous solution of CaCl2. The ion exchange was repeated three times the zeolite washed thoroughly with distilled water and dried undervacuum (6 × 10–4 torr)at 100 °C for approximately 24 h prior to use. The occupancy (<S> ≈ 1.5 molecules of 1,5-DTCO per supercage) was calculated assuming a composition of the unit cell of Si138.7Al53.3Na7.5Ca23.3O384 as reported by K. Pitchumani, P. H.

  14. CaY turned yellow instantaneously upon mixing of 1,5-DTCO and the zeolite. Gas chromatographic monitoring of the hexane slurry was conducted approximately 10 min after addition of the 1,5-DTCO to the CaY and revealed > 96% absorption had already occurred.
