Tetrathiotetracene thin film morphology and electrical properties (2015)
Journal Article
Pudzs, K., Vembris, A., Busenbergs, J., Rutkis, M., & Woodward, S. (in press). Tetrathiotetracene thin film morphology and electrical properties. Thin Solid Films, 598, https://doi.org/10.1016/j.tsf.2015.11.087

The electrical properties of organic thin films are determined by their chemical constituents and the morphology of the films deposited. In this paper the morphology of vacuum sublimed (7∙10-6 mbar) tetrathiotetracene (TTT) thin films is shown to be... Read More about Tetrathiotetracene thin film morphology and electrical properties.

Asymmetric pentafulvene carbometalation-access to enantiopure titanocene dichlorides of biological relevance (2015)
Journal Article
Cini, M., Bradshaw, T. D., Woodward, S., & Lewis, W. (2015). Asymmetric pentafulvene carbometalation-access to enantiopure titanocene dichlorides of biological relevance. Angewandte Chemie International Edition, 54(47), https://doi.org/10.1002/anie.201508034

Unprecedented asymmetric copper-catalyzed addition of ZnEt2 (ZnBu2) to the exocyclic C[DOUBLE BOND]C bond of pentafulvenes C5H4([DOUBLE BOND]CHAr) (Ar=2-MeOPh and related species) results in enantiomerically enriched (up to 93:7 e.r.) cyclopentadieny...

One-pot Cannizzaro cascade synthesis of ortho-Fused Cycloocta-2,5-dien-1-ones from 2-Bromo(hetero)aryl aldehydes. Angewandte Chemie International Edition, 54(36), https://doi.org/10.1002/anie.201505347

An intramolecular Cannizzaro-type hydride transfer to an in situ prepared allene enables the synthesis of orthofused 4-substituted cycloocta-2,5-dien-1-ones with unprecedented technical ease for an eight-ring carboannulation. Various derivatives coul... Read More about One-pot Cannizzaro cascade synthesis of ortho-Fused Cycloocta-2,5-dien-1-ones from 2-Bromo(hetero)aryl aldehydes.

Anionic sigmatropic-electrocyclic-Chugaev cascades: accessing 12-aryl-5-(methylthiocarbonylthio)tetracenes and a related anthra[2,3-b]thiophene (2015)
Journal Article
Burroughs, L., Ritchie, J., Ngwenya, M., Khan, D., Lewis, W., & Woodward, S. (2015). Anionic sigmatropic-electrocyclic-Chugaev cascades: accessing 12-aryl-5-(methylthiocarbonylthio)tetracenes and a related anthra[2,3-b]thiophene. Beilstein Journal of Organic Chemistry, 11, https://doi.org/10.3762/bjoc.11.31

1,4-Diols resulting from the double addition of ArCCLi (Ar = Ph, substituted phenyl, 2-thienyl) to ortho-C6H4(CHO)2 undergo cascades to tetracenes on simple admixture of LiHDMS, CS2 and MeI. Acene formation proceeds by [3,3]-sigmatropic rearrangement...
