Synthesis of conjugated diallenes by double [2,3]-sigmatropic rearrangement of conjugated diyne trichloromethanesulfenates

The preparation of several 2,4-diyne-1,6-diols and their esterification with trichloromethanesulfenyl chloride is described. The thus generated bis- propargylic trichloromethanesulfenates undergo spontaneous double [2,3]- sigmatropic rearrangement which leads to the formation of conjugated diallenic trichloromethyl sulfoxides in good to excellent yields.

Synthesis of 5,10,15,20-meso-unsubstituted and 5,10,15,20-meso-substituted- 21,23-ditellura/diselena core-modified porphyrinogens: Oxidation and detection of mercury(ii)

Tellurium and selenium incorporated 5,10,15,20-meso-unsubstituted-21,23- ditellura/diselena core-modified porphyrinogens (N2Te2 and N2Se2), 5,10,15,20-meso-unsubstituted-21-tellura/selena core-modified porphyrinogens (N3Te and N3Se) and fully substituted meso-carbons porphyrinogens (N2Te2, N 2Se2 and higher analogs) are synthesized by 3 + 1 condensation of tellurophene/selenophene dipyrranes and their corresponding diols in the presence of BF3-etharate or BF3-methanol. The meso-unsubstituted and substituted porphyrinogens were oxidized with chloranil/0.1% aqueous FeCl3 in CHCl3 at room temperature to obtain the corresponding porphines and porphyrins which are further reduced to corresponding chlorin and bacteriochlorin, whereas the fully meso-substituted porphyrinogens were found to be good ligands for Hg2+. The structures of the products were characterized by IR, 1H, 13C, 125Te, 77Se NMR, CHN analysis, mass spectrometry and single-crystal XRD.

Selectivity in the Ruthenium-catalyzed Alder ene reactions of di- and triynes

Ruthenium-catalyzed Alder ene reactions between diynes and triynes with terminal alkenes gave the corresponding enynes and enediynes with high regio- and site-selectivity. The selectivity profile clearly indicates that one of the alkynyl moieties of 1,3-diynes not participating in the reaction determines the regiochemistry, whereas the interplay between steric hindrance and polar substituents at the propargylic sites determines the site-selectivity.
