• Synthesis of stilbene analogues by one-pot oxidation-Wittig and oxidation-Wittig–Heck reaction

  Synthesis of symmetrical (and unsymmetrical) stilbene derivatives is achieved by a combination of one-pot steps of Kornblum type oxidation of benzyl halide, its simultaneous in situ formation of phosphonium salt, and subsequently their Wittig reaction. In other variant it is oxidized to aldehyde, treated with ylide generated from phosphonium salt (CH3PPh3X) to give styrene, and subjected to Pd catalyzed

  对称（和不对称）二苯乙烯衍生物的合成是通过将一锅法的Kornblum型苄基卤化物氧化，同时同时原位形成phospho盐以及随后的Wittig反应相结合来实现的。在另一变体中，将其氧化成醛，用由salt盐（CH 3 PPh 3 X）产生的内鎓盐处理以得到苯乙烯，并与芳基卤化物进行Pd催化的Heck反应，以三步一锅法得到丁苯二酚。
• One-pot synthesis and study of spectroscopic properties of oligo(phenylenevinylene)s

  Two series of OPVs (oligo(phenylenevinylene)), that is, ((1E,1'E)-(2,5-dimethoxy-1,4-phenylene)bis (ethene-2,1-diyl))dibenzene derivatives and 4-((E)-4-((E)-styryl)styryl)pyridine derivatives with different functional groups of varying electronic properties have been synthesized by one-pot Wittig-Heck methodology. The synthesized derivatives have been studied for their optical properties. Amongst them the ((1E,1'E)-(2,5-dimethoxy-1,4-phenylene)bis(ethene-2,1-diyl))dibenzene derivatives with appropriate changes in the end group showed a significant impact on the UV absorption and emission spectra. Particularly NO2-OPV showed distinct solvatochromism in the wavelength range of 218 nm in different solvents. Whereas 4-((E)-4((E)-styryl)styryl)pyridine derivatives showed clear acidochromism which can be detected visually as well as spectroscopically. (C) 2015 Elsevier Ltd. All rights reserved.
• Solid State Behaviour of Vinyl Quinones

  2,5-Bisvinyl-1,4-benzoquinones 1 and 2-vinyl-1,4-benzoquinones 2 substituted with aryl or ester end groups have been synthesized. The 2,5-bisstyryl-1,4-benzoquinones 1 (R=phenyl, p-tolyl, o-tolyl) crystallize with a 7 Angstrom-stacking axis. But only for the o-tolyl derivative the contacts between the vinyl groups are close enough to allow a four-center type photopolymerization. The ester derivative 1 (R=COOEt) has a layer structure and can be photooligomerized in the crystal. The generated cyclobutane subgroups have twofold symmetry. The vinylquinones 2 (R=aryl) may be dimerized photochemically in the crystal at the vinyl groups to centrosymmetric cyclobutanes. Crystals with 4 Angstrom stacking axis are also photoreactive.
