An efficient, transition metal‐free procedure for the cyclopropanation of alkenes using malononitrile and the LiI‐tBuOCl combination under mild reaction conditions is described. The reaction mechanism most likely involves tBuOI generated in situ from LiI and tBuOCl. The utility of this new methodology has been demonstrated by the synthesis of a potential HIV‐1 RT inhibitor.

convenient low-cost method for regioselective ring-opening of donor–acceptor cyclopropanes with the Zn-AcOH reductive system was developed. The general character of the method was displayed via efficient reduction of a representative series of 2-(het)arylcyclopropane-1,1-diesters as well as donor–acceptor cyclopropanes with other types of electron-withdrawing activating groups. This method opens a rapid
regioselective ringopening of donor–acceptorcyclopropanes without the addition of any catalyst. 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 ringopening of donor–acceptor cyclopropanes
