Spontaneous oxidation of a sulfide in zeolite CaY: the unprecedented reaction of a sulfide radical cation with oxygen
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.
