REACTION OF SULFENYL HALIDES WITH ALKENES IN THE PRESENCE OF PERCHLORIC ACID

In the reaction of 2,4-dinitrobenzenesulfenyl chloride and benzenesulfenyl chloride with cyclohexane, propene, and styrene in acetic acid in the presence of perchloric acid the corresponding solvent adducts are formed with yields of 47-75percent.The effect of the perchloric acid on the rate of the reaction of 2,4-dinitrobenzenesulfenyl chloride with cyclohexene is described by an equation for homogeneous catalysis.On the basis of the kinetic data two possible schemes are proposed for the effect of perchloric acid on the formation of the solvent adducts, i.e., a mechanism of homogeneous catalysis and by an ion-exchange mechanism in the noncontrolling stages of the reaction.
O-SILYLATED ENOLATES IN ORGANIC SYNTHESIS: SULPHUR-MEDIATED ALKYLATION OF ESTERS WITH ALKENES.

O-Silylated ester enolates can be alkylated, under ZnBr2-catalysis, by the PhSCl-adducts of mono- and di-substituted alkenes to give γ-phenylthioesters, from which sulphur can be removed both reductively and oxidatively.This alkene carbosulphenylation rea
ALKENE CARBOSULPHENYLATION AND CARBOSELENYLATION: THE USE OF ALLYLTRIMETHYLSILANE AND O-SILYLATED ENOLATES.

Allyltrimethylsilane, as well as O-silylated enolates, can be alkylated by the PhSCl adducts of alkenes and vinyl ethers (1, X=SPh); the PhSeCl analogues (1, X=SePh), however, are less useful for alkylation purposes due to competing nucleophilic attack at selenium.
