Carbopalladation-sulphonylation of allene: A versatile preparation of 2-vinyl or 2-aryl allyl sulphones

The allene carbopalladation process can be realized with various vinylic or aromatic derivatives, in the presence of sodium benzenesulphinate, and allows the preparation of the entitled sulphones.

A New Synthesis of Olefins via the Elimination Reaction of β-Tributylstannyl Organosulfur Compounds

Organosulfur compounds on treatment with butyllithium in tetrahydrofuran followed by tributylstannylmethyl iodide 1 afforded olefins.The reaction was found to proceed via the destannylsulfurization of the initially formed β-stannyl organosulfur compounds.Thus, allyl 2-pyridyl sulfides 2 or allyl phenyl sulfones 12 were converted into 1,3-dienes 4.Compounds 13 and 15 were converted into the olefins 14 and 17.Furthermore, the reaction was applied to the synthesis of α-substituted vinyl sulfides 24 and allene 27.The stereochemistry of the double bond is discussed.Keywords - destannylsulfurization; allyl 2-pyridyl sulfide; allyl phenyl sulfone; synthesis of olefin; 1,3-diene; vinyl sulfide; β-tributylstannyl organosulfur compound.

LEWIS ACID INITIATED OR HIGH PRESSURE PROMOTED REACTIONS OF ISOPRENE WITH PHENYLSULFINYL CHLORIDE

Lewis acid initiated reaction of isoprene with PhSOCl proceeds in a ene fashion with the formation of 2-phenylsulfinylmethyl-1,3-butadiene.High pressure promoted addition produces Z-1-phenylsulfinyl-4-chloroadduct presumably via cycloaddition.

3-Chloro-2-chloromethyl-4-(4-chlorophenoxy)-1-butene as a Functionalized Isoprene Unit. An Electrochemical Preparation and Some Reactions

3-Chloro-2-chloromethyl-4-(4-chlorophenoxy)-1-butene (1) was prepared in 72percent yield by electrooxidative double ene-type chlorination of 1-(4-chlorophenoxy)-3-methyl-2-butene.The electrolysis was conducted at room temperature in a two layer solvent sy

REACTION OF 1,3-DIENES WITH ARYLSULFONYL THIOCYANATES

At room temperature arylsulfonyl thiocyanates add to conjugated dienes with the formation of 1,4-addition products.In all cases the organic sulfonyl radical is fixed at the least substituted carbon atom of the 1,3-diene system.In reaction with triethylamine or sodium ethoxide the adducts which form eliminate thiocyanic acid with the formation of conjugated dienyl sulfones.
