S. Vincent et al., SELECTIVE OXIDATION OF SULFIDES TO SULFOXIDES BY ATMOSPHERIC OXYGEN AND ALDEHYDE CATALYZED BY NI-II COMPLEXES, Phosphorus, sulfur and silicon and the related elements, 92(1-4), 1994, pp. 189-192
A new and efficient method for oxidising sulfides selectively to sulfo
xides has been developed with atmospheric oxygen, in the presence of i
sobutyraldehyde and catalysed by Ni-II complexes such as 3-bis-(p-meth
oxyphenyl)-1,3-propanedionato]nickel, [Ni(dmp)(2)], and bis[acetylacet
onato]nickel, [Ni(acac)(2)].
