Abstract
A synthesis of two ionic liquid-supported iodosylbenzenes,1-(4-iodosylbenzyl)pyridinium tetrafluoroborate and 1-(4-iodosylbenzyl)-3-methylimidazolium tetrafluoroborate, which are potentially useful oxidising agents in organic synthesis is reported. Both compounds are stable, active, and easy to handle. The chemical structures of both compounds were characterised by 1H NMR, 13C NMR, IR, MS and elemental analysis.

Abstract
1,2-Diols, aldehydes, and ketones are important intermediates in chemical synthesis, and alkenes are possible precursors for 1,2-diols, aldehydes, and ketones. Herein, novel and environmentally benign methods for palladium-catalyzed dihydroxylation and oxidative cleavage of olefins with oxygen as sole oxidant are presented. The cleavage reactions were performed with acid as additive in aqueous solution, whereas 1,2-diols were formed in the presence of base. A broad substrate scope has been demonstrated allowing monosubstituted aromatic and aliphatic terminal alkenes, 1,2-disubstituted, and 1,1-disubstituted olefins. The cleavage reactions of dioxo-Pd(II) complexes implicate 1,2-diol might act as a key intermediate of olefin cleavage.

Abstract
The sodium periodate mediated oxidative cleavage of the C-C bond of twelve epoxides is reported with yields of the corresponding carbonyl compounds in up to 91%. This is a two-step reaction that proceeds through a rate-limiting epoxide opening to a vicinal diol that is cleaved in situ to the corresponding carbonyl compound. This method serves as a chemoselective alternative to ozonolysis.
