Intramolecular carbonickelation of alkenes
The efficiency of the intramolecular carbonickelation of substituted allylic ethers and amines has been studied to evaluate the influence of the groups borne by the double bond on this cyclization. The results show that when this reaction takes place, it affords only the 5-exo-trig cyclization products, viz. dihydrobenzofurans or indoles. Depending on the tethered heteroatom (O or N), the outco...
متن کاملBromination of Alkenes
The two most common halogenation reactions are chlorination and bromination. The addition of these halogens to alkenes yields 1,2-dihalides. Chlorinations reactions are used to synthesize over 6 million tons per year of ethylene dichloride (1,2-dichloroethane) for use as a solvent and for subsequent polymerization to produce poly(vinylchloride) known more commonly as PVC which is used for plumb...
متن کاملElectrophilic monoiodination of terminal alkenes.
An excess of elemental iodine in N,N-dimethylacetamide enables effective 3/iodanylium-de-hydronation of terminal alkenes with 3-iodopropene derivatives and hydrogen iodide formation within minutes at room temperature. The optimal molar ratio of iodine to substrate was decreased to 1 : 1 when hydrogen iodide formed was oxidized on a platinum anode. The electrolytic oxidation recovers iodine as a...
متن کاملHypoiodite-mediated cyclopropanation of alkenes.
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.
متن کاملStereoselective synthesis of Z-alkenes.
This chapter offers a general review of the evolvement of methods for the stereoselective synthesis of Z-alkenes, with a focus on the development of catalytic systems towards this goal in recent years.
