Aldol Condensation of β-Diketones and β-Ketoesters with Aldehydes Catalyzed by Samarium (III) Iodide

Abstract Catalyzed by SmI3 β-diketones and β-ketoesters condense with aldehydes to give benzylidene substituted β-diketones and β-ketoesters at room temperatures in fair yields.

A Facile Route to Synthesize α,α′-bis(Substituted-benzylidene) Cycloalkanones Promoted by SmI3

Abstract Promoted by SmI3 cycloalkanone trimethylsilyl enol ethers were reacted with aldehydes to give α,α′-bis (substituted-benzylidene) cycloalkanones.

Allylation of Imines with Samarium/Allyl Bromide System

Abstract Imines can be readily allylated with samarium/allyl bromide system to afford homoallylamines in satisfactory yields in THF under mild conditions.

Six Membered Ring Opening of Isopropylidene Malonate Derivatives: Synthesis of α,β-Unsaturated Thio- and Selenoaryl Carboxylic Esters

Abstract Six membered rings of isopropylidene malonate derivatives were opened by aryl thiolate anions and aryl selenolate anions which were produced through reductive cleavage of diaryl disulfides and diaryl diselenides with SmI2, and the substituted propenoic acid selenoaryl and thioaryl esters were synthesized.

A NOVEL SYNTHESIS OF ALLYL AND PROPARGYL SELENIDES PROMOTED BY INDIUM

Abstract Promoted by indium, allylic and propargyl bromides react with diorganyl diselenides in THF to give allylic and propargyl selenides in moderate to good yields.

Gallium Mediated Allylation and Propargylation of 1-(α-Aminoalkyl)benzotriazole: An Alternative Route to Homoallylic and Homopropargyl Amines

Abstract Mediated by gallium metal 1-(α-aminoalkyl)benzotriazole reacted with allylic and propargyl bromide to give homoallylic and homopropargyl amines in moderate to good yields.

An alternative route to 1,3-diketones promoted by samarium diiodide

Abstract SmI 2 promoted condensation of α-haloketones with carboxylic acid chlorides or anhydrides leads to 1,3-diketones.

Aromatic Nucleophilic Substitution with Aryltellurolate lons Produced Through Reductive Cleavage of Diaryl Ditellurides by Samarium Diiodide

Abstract Aryltellurolate ions which were obtained from diaryl ditellurides by reductive cleavage in the aid of SmI2 undergo nucleophilic substitution reaction on aromatic rings and a series of new unsymmetrical diaryl tellurides were synthesized.

β-Diketone Synthesis by Reaction of α-Haloketones with Acid Chlorides or Acid Anhydrides Promoted by Samarium Triiodide

Abstract Promoted by SmI3, α-haloketones were reacted with acid chlorides or acid anhydrides and β-diketones were synthesized via intermediate samarium enolates.

Aromatic Nucleophilic Substitution by Arylselenolate Ions Produced Through Reductive Cleavage of Diaryl Diselenide Induced by SmI2-THF-HMPA System

Abstract Arylselenolate Ions which were produced through reductive cleavage of Se-Se bond in diaryl diselenide undergo nucleophilic substitution on aromatic rings and a series of new unsymmetrical diaryl selenides were synthesized.
