Journal ArticleDOI
Reverse cope elimination of hydroxylamines and alkenes or alkynes: theoretical investigation of tether length and substituent effects.
Elizabeth H. Krenske,Edwin C. Davison,Ian Thomson Forbes,Jacqueline A. Warner,Adrian L. Smith,Andrew B. Holmes,Andrew B. Holmes,Kendall N. Houk +7 more
TL;DR: Competition experiments have shown that tethering the hydroxylamine to the alkene or alkyne can reverse the reactivity order from that normally observed, and a range of density functional theory methods and CBS-QB3 calculations predict that the activation energies for intramolecular reverse Cope eliminations follow the order 6-exo-dig < 5- exo-trig < 7-Exo-Dig ≈ 7-exO-dig.
Journal ArticleDOI
Polymer supported chromium porphyrin as catalyst for polycarbonate formation in supercritical carbon dioxide.
Louise M. Stamp,Stephan Mang,Andrew B. Holmes,Kevin A. Knights,Yolanda R. de Miguel,Ian F. McConvey +5 more
TL;DR: A new polymer-supported chromium porphyrin has been prepared and fully characterised; its catalytic activity and recyclability were investigated for the ring-opening copolymerisation of 1,2-cyclohexene oxide (CHO) and carbon dioxide (CO2).
Journal ArticleDOI
Synthesis of 4-alkyl-1-trimethylsilylbuta-1,3-diynes
Andrew B. Holmes,Graham E. Jones +1 more
TL;DR: Lithium trimethylsilylbutadiyne (2) is alkylated by primary alkyl halides in THF-HMPA or via the ethylenediamine complex (4) in ThF-DMSO to give the title compounds.
Journal ArticleDOI
Selective desilylation of bis(trimethylsilyl)acetylenes
Andrew B. Holmes,Clive L. D. Jennings-White,Adrian H. Schulthess,Bassey Akinde,David R. M. Walton +4 more
TL;DR: In this article, it was shown that bis(trimethylsilyl)acetylenes with 1-10 mol% KF-18-crown-6 ether can be obtained by quantitative monodesilylation with MeLiLiBr complex.
Journal ArticleDOI
Inverted semi-transparent organic solar cells with spray coated, surfactant free polymer top-electrodes
Alexander Colsmann,Manuel Reinhard,Tae-Hyuk Kwon,Christian Kayser,Felix Nickel,Jens Czolk,Uli Lemmer,Noel Clark,Jacek J. Jasieniak,Andrew B. Holmes,David J. Jones +10 more
TL;DR: In this paper, spray-deposition of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) buffer layer or top-electrode from aqueous solution on a non-polar active layer in inverted organic solar cells is commonly considered a very challenging task.
