Functionalised Trimethyltetrathiafulvalene (TriMe-TTF) Derivatives via Reactions of Trimethyltetrathiafulvalenyllithium with Electrophiles: X-ray Crystal Structures of Benzoyl-TriMe-TTF and Benzoylthio-TriMe-TTF
A new series of tetrathiafulvalene (TTF) molecules with extended π-system was prepared by using a Wittig reaction to generate the TTF key. The process of deprotection-alkylation of thiolates provided access to a wide variety of molecules. The study of their reducing power was carried out by cyclic voltammetry. Charge transfer complexes have also been chemically prepared by using TCNQ as an electron
The synthesis of new derivatives of 9,10-bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene has been achieved by two different routes. Deprotonation of 8 using LDA in THF at −78 °C, followed by in situ quenching of the lithiated intermediate 9 with N,N-dimethylformamide, N-methyl isothiocyanate and methyl chloroformate gave aldehyde, thioamide and methyl ester derivatives 10-12, respectively. Sulfur
The scope and limitations of the synthesis of unsymmetrically substituted TTF derivatives via the “phosphonate way” was investigated using as precursors 1,3-dithiol-2-yl-phosphonates and 1,3-dithiol-2-yliden iminium salts with various substitutents on the dithiole cycles.
