Syntheses of the bis(heterocycle)-fused bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives 7 and 8, the heterocycle-fused BEDT-TTF, methylenedithio(ethylenedithio)tetrathiafulvalene (MET), and ethylenedithiotetrathiafulvalene derivatives 9-11, and the 1,3-dioxolane derivative of MET 12a and its analogues 12b-d are described. The heterocycle-fused ketones 17 and 19 with cis ring fusions could be prepared by the BF3-promoted reaction of tin dithiolate 13 with dihaloheterocycles 15 and 16 in good yields, respectively, and served as key intermediates for the (RO)3P- and/or Me3Al-promoted coupling syntheses of these new tetrathiafulvalene donors 7-12. Further, the electrochemical properties of new donors 8-12 by the use of cyclic voltammetry and the molecular structures of 9a, 10a, 11, and 12a by X-ray crystallographic analyses are also reported.

[2+4]-Cycloaddition of 2,3-dihydro-1,4-dithiine and oligomeric 1,3-dithiol-2,4,5-trithione results in the formation of 4a,6,7,8a-tetrahydro-1,3-dithiolo[4′,5′:5,6]-[1,4]dithiino[2,3-b]-1, 4-dithiine-2-thione, which is a precursor for synthesis of new organic π-donors.

A stereoselective synthetic method is reported for the molecular framework found in common daucane and isodaucane sesquiterpenoid natural products. The synthetic method constitutes a scalable, modular, and also asymmetric access to a complex natural product scaffold, wherein the substitution pattern and the stereochemistry can be adjusted simply by choosing different starting materials. The method allows the rapid introduction of diverse heterocyclic substructures such as (benzo)furans, (benzo)thiophenes, dithiins, thiazoles, and indoles, which actually also facilitate and direct the key intramolecular annulation step.

Paragraph 0032; 0035-0037, (2017/04/03)
The invention discloses an organic-inorganic hybridization molecular magnet with room-temperature metallicity and a preparation method of the molecular magnet. The molecular formula of the molecular magnet with the room-temperature metallicity is BETS3[Cu2(C2O4)3]B2, wherein BETS represents disulfo-diethylene tetraselenafulvalene; and B represents an alcohol compound. The preparation method of the molecular magnet with the metallicity comprises the step of performing electrochemical reaction on an ammonium salt of cupric oxalate with BETS in an electrochemical tank by taking the alcohol compound as an electrolyte solution so as to obtain the molecular magnet with the room-temperature metallicity on an anode. According to the preparation method of the molecular magnet with the room-temperature metallicity, single crystal of the molecular magnet with room-temperature metallicity is prepared in an organic solvent system from an organic pi electron system and Jahn-Teller distorted magnetic anion. The molecular magnet with room-temperature metallicity, which is provided by the invention, is good in crystal quality, single in product and high in yield.

SYNTHESIS AND CONFORMATIONAL ANALYSIS OF GLYOXAL BIS-DITHIOACETALS: 1,4,5,8-TETRATHIADECALIN (HEXAHYDRO-1,4-DITHIINO-1,4-DITHIIN) AND TRANS-2,3-BIS(METHYLTHIO)-1,4-DITHIANE

The synthesis of the first examples of two new classes of glyoxal bis-dithioacetals: trans-1,4,5,8-tetrathiadecalin and trans-2,3-bis(methylthio)1,4-dithiane, has been performed.The conformation of 2,2'-bis-1,3-dithiolane and trans-2,3-bis(methylthio)-1,4-dithiane in CDCl3 solution has been studied using (1)H NMR techniques.In the first case an antiperiplanar conformation has essentially been found whereas a 83/17 mixture of diaxial and diequatorial conformers has been observed in the second.
