Extremely high stereospecificity (up to 100percent diastereoisomeric purity) can be obtained for the metallic salts induced radical cyclisation of the cis and trans 1-methyl 4-hexenyl N-chloroamines.A possible mechanism for the highly effective trans-addition using metal-complexed aminyl radical is proposed.

A practical, general and efficient protocol for the catalytic epoxidation of alkenes has been developed.The in situ generation of reactive dioxiranes capable of epoxidizing a variety of alkenes under biphasic conditions has been accomplished using phase transfer catalysts bearing a carbonyl group.Optimal epoxidation conditions employ 10 mol percent of 1-dodecyl-1-methyl-4-oxopiperidinium triflate (8d(+)OTf(-)) in a CH2Cl2/pH 7.5-8.0 biphase using potassium monoperoxosulfate (Oxone) as the oxidant.Optimization of the conditions identified (1) slow addition rate, (2) pH 7.5-8.0, (3) N-dodecyl chain, and (4) the triflate salt as key experimental and structural variables.A selection of nine olefins was successfully oxidized to the corresponding epoxides in 83-96percent yield.
REACTIONS OF ORGANIC HALIDES WITH OLEFINS UNDER Ni0-CATALYSIS. FORMAL ADDITION OF HYDROCARBONS TO CC-DOUBLE BONDS

The reaction of various types of organic halides with electron deficient olefins under the influence of NiCl2 x 6 H2O in the presence of zinc and pyridine leads to formal addition products of hydrocarbons to CC-double bonds in good yield.
