A step toward polytwistane: Synthesis and characterization of C 2-symmetric tritwistane

Twistane is a classic hydrocarbon with fascinating stereochemical properties. Herein we describe a series of oligomers of twistane that converges on a chiral nanorod, which we term polytwistane. A member of this series, C 2-symmetric tritwistane, has been synthesized for the first time. This journal is The Royal Society of Chemistry.

1-Benzenesulfonyl-2-trimethylsilylacetylene: a New Acetylene Equivalent for the Diels-Alder Reaction

1-Benzenesulfonyl-2-trimethylsilylacetylene has been shown to be an effective acetylene equivalent for the Diels-Alder reaction.

The Radical Cations of Bicyclohepta-2,5-diene (8,9,10-Trinorborna-2,5-diene) and Bicycloocta-2,5-diene (2,3-Dihydrobarrelene). An ESR and ENDOR Study

The radical cation of bicyclohepta-2,5-diene (8,9,10-trinorborna-2,5-diene; 1) in CF2ClCFCl2 and CF3CCl3 matrices and that of bicycloocta-2,5-diene (2,3-dihydrobarrelene; 2) in CFCl3 and CF3CCl3 matrices have been studied by ESR and ENDOR spectroscopy.For 1+., the coupling constants of the olefinic, methano-bridge, and bridgehead protons are -0.780 +/- 0.005, +0.304 +/- 0.002, and -0.049 +/- 0.002 mT, respectively.The hyperfine tensor for the methano-bridge protons is axial.A = +0.263 +/- 0.002 and A = +0.386 +/- 0.002 mT, while that for the olefinic protons is orthorhombic, Ax = -0.594 +/- 0.005, Ay = -0.913 +/-0.005, and Az = -0.834 +/- 0.005 mT (x parallel to C-H bond, z parallel to 2p? axis).For 2+., the coupling constants of the olefinic, ethano-bridge, and bridgehead protons are -0.68 +/- 0.01, +0.162 +/- 0.005, and -0.108 +/- 0.005 mT, respectively.The hyperfine data for 1+. and 2+. fully support the presentation of their singly occupied orbitals as antisymmetric combinations, b2(?), of the two bonding ethene ?-MO's.
