- Catalyst-Free, Regioselective Ring Opening of Donor-Acceptor Cyclopropanes: Synthesis of Functionalized Mono- and Disulfides
-
Interesting sulfur compounds such as monosulfides, symmetrical disulfides, unsymmetrical disulfides, and other 1,3-bifunctionalized compounds were synthesized using benzyltriethylammonium tetrathiomolybdate, [BnNEt3]2MoS4, as the sulfur transfer reagent via regioselective ring opening of donor-acceptor cyclopropanes without the addition of any catalyst.

- The first synthesis of nitro-substituted cyclopropanes and spiropentanes via oxidation of the corresponding amino derivatives
-
A novel approach to nitro-substituted cyclopropanes and spiropentanes via oxidation of the corresponding amines with dimethyldioxirane is reported. The method is used successfully for the preparation of a series of nitrocyclopropanes as well as for the first synthesis of 1,4-dinitrospiro[2.2]pentane.

- Cyclopropanation of olefins with nitromethane
-
A procedure for the use of nitromethane as an iodonium ylide precursor has been developed. Electron-rich olefins are cyclopropanated with nitromethane in the presence of bis(acetoxy)iodobenzene, a base and a Rh(II) catalyst to provide nitrocyclopropanes i
