Hydrogenation and isomerization of allyl alcohol and 3-cyclohexenol in presence of the chloromethyl methyl sulfoxide complexes of palladium and rhodium

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1973
1. The chloromethyl methyl sulfoxide complex of Pd catalyzes the hydrogenation of the C=C bond of allyl alcohol (AA) and 3-cyclohexenol, and also their rearrangement respectively to propionaldehyde and cyclohexanone. 2. The chloromethyl methyl sulfoxide complex of Rh accelerates the hydrogenation of AA and also its rearrangement, either ...

Regiodivergent Synthesis of Methylene and Methyl Ring-Fused Isoquinolinones: Base-Promoted Isomerization of N-Allyl Amides.

Journal of Organic Chemistry, 2022
Methylene and methyl tricyclic isoquinolinones were selectively prepared using a palladium(II)-catalyzed aerobic aza-Wacker reaction, followed by a base- and temperature-controlled Heck reaction catalyzed by palladium(0).

Selectfluor-Promoted Reactions of Aryl Methyl Ketones with Dimethyl Sulfoxide to Give 2,5-Diacylthiophenes and β-Acyl Allylic Methylsulfones

Organic Letters, 2023
In this paper, a convenient synthesis of 2,5-diacylthiophenes and β-acyl allylic methylsulfones from aryl methyl ketones with dimethyl sulfoxide (DMSO) through Selectfluor-promoted cascade cyclization and cross-coupling reactions by simple solvent modification is described. This method enables the formation of new C-C and C-S bonds via the selection of

Stereoselective Preparation of Bicyclo[3.3.0]octanones From the Products of Aprotic Conjugate Addition of Lithiated Allylic Sulfoxides to Cyclopent-2-enone and Enolate Trapping With Methyl Cyanoformate

Australian Journal of Chemistry, 1989
The lithium enolates arising by aprotic conjugate addition of lithiated but-2-enyl sulfoxides and a phosphine oxide to cyclopent-2-enone react efficiently with methyl cyanoformate to give the corresponding methyl 5-oxocyclopentanecarboxylates in good yields.

Über methyl‐halogenierte Allyl‐methyl‐sulfoxide und ‐sulfone und die Darstellung halogenierter Sulfine

Chemische Berichte, 1986
AbstractDie Allyl‐methyl‐sulfoxide R1R2R3CS(O)CH2CHCH2 1a–7a (R1, R2, R3 = H, F, Cl, CF3) sowie die entsprechenden Sulfone 1b–7b wurden dargestellt. Die an der Methylgruppe substituierten Sulfoxide stehen im Gleichgewicht mit Sulfensäure‐allylestern R1R2R3CSOCH2CHCH2 in Abhängigkeit von der Temperatur und der Art der Substitution.
