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.

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.

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.

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.
