[4+2] Cycloaddition of C60 to 2-(thi)oxo-4,5-bis(methylene)-1,3-dithioles: en route to the bis-linking of tetrathiafulvalene to C60

Abstract The title reaction carried out from S-propargyl xanthate 3 or 2-(thi)oxo-4,5-bis(bromomethyl)-1,3-dithioles 4a and 4b with C60 is presented and some conversions of the synthesized cycloadducts 2a and 2b in several 1,3-dithiole derivatives are described.

A new strategy to reach highly extended and quinonoid tetrathiafulvalene (TTF) derivatives

Abstract 2,3-Bis(bromomethyl)TTFs 4 are used as precursors of 2,3-dimethylene-[2H]-TTFs 5 to reach cycloadducts of high synthetic interest via a [4+2] cycloaddition with quinonic derivatives. Subsequent Horner-Wadsworth-Emmons olefinations with a 1,3-dithiole phosphonate anion afforded highly extended and sulfur-rich analogs of tetrathiafulvalene 1.

Extensively conjugated tetrathiafulvalene (TTF)π-electron donors with oligothiophenes spacer groups

New extended p-donors combining the tetrathiafulvalene (TTF) system with the conjugated backbone of substituted terthienyls are described.

A facile access to masked isobenzofurans ; High exo-stereoselectivity in the Diels-Alder reactions of 4,7-dihydro-4,7-ethanoisobenzofuran.

Abstract The isobenzofuran derivatives precursors 4 a-c are readily prepared from 1 ; their Diels-Alder adducts with cis-dienophiles present a stereochemistry endoexo from 4 b,c and, interestingly, only exo (towards the furan moiety) from 4 a.

A novel array in extended tetrathiafulvalenes (TTF): the ‘H’ shape

The highly extended, cross-conjugated and sulfur rich π-electron donor 2a was synthesized and characterized introducing the ‘H’ shape as a new approach in the tetrathiafulvalene (TTF) array.

Synthesis and properties of new 2-mono and 2,3-bis(hydroxymethyl)-6,7-ethylenedithio TTF vinylogs

Abstract The synthesis of title compounds prone to generate hydrogen bonds thanks to their alcohol functionalities is depicted. Cyclic voltammetry proves these derivatives to be strong π-donors, able to act as convenient precursors of related organic metals.

Bis(trisubstituted tetrathiafulvalenyl) disulfides: Disulfide-bridged TTF dimers

Abstract The title compounds are synthesized, using the oxidative coupling of TTF thiolates. The disulfide linkage induces approximate orthogonality between the two TTF units, while maintaining virtually unchanged their electrochemical properties.

Versatility of cycloaddition of electrophilic alkynes to η2-CS2 metal complexes. Reversible isomerisation of 1,3-dithiol-2-ylideneiron and heterometallocyclic complexes

The 1,3-dithiol-2-ylideneiron(0) complexes (3) isomerise to heterometallocycles (4), the equilibrium constant and rate constant increasing with donor strengths of the ligands on iron.

Novel highly extended and sulfur rich tetrathiafulvalene (TTF) derivatives through an unprecedented TTF core building process

A new and unexpected tetrathiafulvalene (TTF) core building process is observed via reaction of a 1,3-dithiole phosphonate anion with a 2-oxo-1,3-dithiole functionality.

(TTF)2[TTF(CO2H)2(CO2)2]: a wholly TTF material containing TTF radical cations and TTF derived anions

Electrooxidation of tetrathiafulvalene (TTF) carried out in the presence of (Bu4N)2TTF(CO2H)2(CO2)2 as supporting electrolyte affords wholly TTF organic materials in which TTF cations are associated with TTF(CO2H)2(CO2−)2 as counteranions.
