- Radical-Cascade Avenue for 3,4-Fused-Ring-Substituted Thiophenes
-
A single-step intramolecular radical cascade reaction of diynes and thioacetic acid in the presence of a catalytic amount of azobis(isobutyronitrile) as a radical initiator has been developed to synthesize thiophenes. This method allows easy and effective construction of a thiophene scaffold having 3,4-fused-ring substitution and unsubstituted 2,5-positions for further functionalization and polymerization. Using this method, derivatives of cyclopenta[c]thiophene, 3,4-ethylenedioxythiophene, and thiophene-containing spirocyclic compound have been synthesized.

- Synthesis and characterization of novel organic heteroatom compounds from reaction of Woollins' reagent with various organic substrates
-
A series of new selenium-containing heteroatom compounds were synthesized in good yields by the reaction of Woollins reagent with various organic substrates such as cyclohexylamine, N-benzoylbenzamide, benzoic anhydride, 4-fluoro-N-(2-oxo-2-phenylethyl)benzamide, N-benzoylbenzamide, benzoic anhydride, 3-(bromomethyl)benzonitrile, 1,2-diphenylethane-1,2-diol, and sodium alcoholate. Three representative X-ray structures are described.

- Improved solubility and stability of trialkylammonium selenocarboxylate in organic solvents for efficient amidation with azides
-
Trialkylammonium selenocarboxylate, formed in situ from the reaction of diacyl diselenide with piperidine in the presence of diisopropylethylamine, was found to react readily at room temperature with electron-deficient azides to form amides in excellent yields. The trialkylammonium selenocarboxylate salt formed has good solubility and stability in organic solvents. The enhanced stability allowed mild heating to improve the amidation yields with electron-rich azides.
