- Anthrathiadiazole Derivatives: Synthesis, Physical Properties and Two-photon Absorption
-
Anthrathiadiazole is a key synthon for the construction of large azaacenes, however, the attachment of different substituents onto the skeleton of anthrathiadiazole is difficult but highly desirable because it could be easy to enrich the structures of aza

- Sulfonimidates: Useful Synthetic Intermediates for Sulfoximine Synthesis via C-S Bond Formation
-
Medicinally relevant sulfoximines are accessed from C-S coupling of sulfonimidates and commercially available organomagnesium reagents. Sulfonimidates are conveniently synthesized by oxidative alkoxylation of readily available sulfinamides. This constitutes a general C-S coupling approach for the synthesis of sulfoximines.

- Aceno[2,1,3]thiadiazoles for field-effect transistors: Synthesis and crystal packing
-
An efficient synthetic approach to a series of aceno[2,1,3]thiadiazole derivatives is described. 2-TIPS and 2-TES molecules exhibited different crystal packings, and 2-TIPS show good device performances with hole mobility up to 0.4 cm2 V-1 s-1 and an average mobility of 0.15 cm2 V-1 s-1 as the active material for organic field-effect transistors. All of the results demonstrate these aceno[2,1,3]thiadiazole derivatives as promising materials for optoelectronic devices.

Sultam of swing: Both enantiomers of 1,2-thiazetidin-3-one oxides were obtained in very good yields with excellent enantioselectivities when using N-heterocyclic carbene catalysts (see scheme; M.S.=molecular sieves, TBS=tert-butyldimethylsilyl). The products were easily converted into 3-oxo-β-sultams, α-mercapto amides, and β-mercapto amines through oxidation or reduction. Copyright

- The synthesis of symmetrical bis-1,2,5-thiadiazole ligands
-
We have been engaged in a search for coordination catalysts for the copolymerization of polar monomers (such as vinyl chloride and vinyl acetate) with ethylene. We have been investigating complexes of late transition metals with heterocyclic ligands. In this report we describe the synthesis of a symmetrical bis-thiadiazole. We have characterized one of the intermediates using single crystal X-ray diffraction. Several unsuccessful approaches toward 1 are also described, which shed light on some of the unique chemistry of thiadiazoles.

The synthesis of various N-monosubstituted trichloromethanesulfinamides by two alternative and novel procedures is described. All these compounds have been found to undergo base-induced elimination of chloroform with formation of the corresponding N-sulfinylamines. Reaction proceeds smoothly under mild conditions.

- Substituted N-aryl alk-1-enesulfinamides: Preparation, properties and conversion into the corresponding indole compounds [1]
-
Reaction of vinylic organometallic derivatives with N-sulfinyl arenamines 2 affords the title sulfinamides 3. On heating their solutions in selected solvents to 80-124 °C, these sulfinamides are converted into the corresponding indoles 6, probably via a [3.3]-sigmatropic rearrangement to intermediates VIII which undergo an intramolecular carbophilic reaction of the nitrogen atom with the neighboring sulfine group, followed by elimination of HSOH. The triethyloxonium tetrafluoroborate- or boron trifluoride etherate catalyzed conversion 3 → 6 can be carried out at a much lower temperature. Elsevier,.

The reactions of N-sulfinylfluoroalkanesulfonyl amines, RfSO2NSO (1), with malonate or dialkyl phosphite gave 1:1 adducts RfSO2NHS(O)Nu , and with alcohols or phenols formed RfSO2NH2 and the sulfites O=S(OR)2 by double addition .Trans-sulfinylation occurred during the reaction of 1 with anilines (C6H5NH2, 4-FC6H4NH2 and C6F5NH2).

- 1,2-Thiazines and Related Heterocycles. Part 1. An Investigation of the Cycloadditions of N-Sulphinylanilines with 1,4-Epoxy-1,4-dihydronaphthalene and Other Alkenes

Evidence is adduced from the character of the alkenes which cycloadd to N-sulphinylanilines and from a kinetic investigation of the reactions of N-sulphinylanilines with 1,4-epoxy-1,4-dihydronaphthalene, examining the effects upon reaction rate of solvent polarity, temperature, and substitution in the N-sulphinylanilines, that the cycloadditions are pericyclic reactions of Diels-Alder type with inverse electron demand.A degree of charge separation in the transition state is indicated but this is small and confined essentially to the sulphinylaniline moiety.
