Thiophene-forming one-pot synthesis of three thienyl-bridged oligophenothiazines and their electronic properties

Beilstein Journal of Organic Chemistry, 2016
The pseudo five-component Sonogashira–Glaser cyclization synthesis of symmetrically 2,5-diaryl-substituted thiophenes is excellently suited to access thienyl-bridged oligophenothiazines in a one-pot fashion. Three thienyl-bridged systems were intensively

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Pseudo five-component synthesis of 2,5-di(hetero)arylthiophenes via a one-pot Sonogashira–Glaser cyclization sequence

Beilstein Journal of Organic Chemistry, 2011
Based upon a consecutive one-pot Sonogashira–Glaser coupling–cyclization sequence a variety of 2,5-di(hetero)arylthiophenes were synthesized in moderate to good yields.

Small molecule branched-chain ketoacid dehydrogenase kinase (BDK) inhibitors with opposing effects on BDK protein levels

Nature Communications, 2023
Branched chain amino acid (BCAA) catabolic impairments have been implicated in several diseases. Branched chain ketoacid dehydrogenase (BCKDH) controls the rate limiting step in BCAA degradation, the activity of which is inhibited by BCKDH kinase (BDK ...

Assembly strategy for thieno[3,2-b]thiophenes via a disulfide intermediate derived from 3-nitrothiophene-2,5-dicarboxylate

Beilstein Journal of Organic Chemistry
A versatile synthetic route to thieno[3,2-b]thiophenes was elaborated from dimethyl 3-nitrothiophene-2,5-dicarboxylate. Nucleophilic substitution of the nitro group with sulfur nucleophiles, including thioacetate or disulfide anions as well as ...

3,5-Bis(4-dodecylthiophen-2-yl)-4H-1,2,6-thiadiazin-4-one

Molbank, 2012
3,5-Dichloro-4H-1,2,6-thiadiazin-4-one 1 reacts with (4-dodecylthiophen-2-yl)trimethylstannane 4 (2.2 equiv.) and Pd(Ph3P)2Cl2 (5 mol%) in acetonitrile at ca. 82 °C to give 3,5-bis(4-dodecylthiophen-2-yl)-4H-1,2,6-thiadiazin-4-one 5 in 93% yield.

Flexible Routes to Thiophenes

, 2014
Three convergent routes to thiophenes are described, hinging on the radical addition of α-xanthyl ketones to ethyl vinyl sulfide or to vinyl pivalate. The latter route ultimately proved to be the most versatile and efficient (61-94%)

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Enhanced Reactivity of [Hydroxy(tosyloxy)iodo]benzene in Fluoroalcohol Media. Efficient Direct Synthesis of Thienyl(aryl)iodonium Salts

Molecules, 2010
In this manuscript, we report clear evidence for the generation of aromatic cation radicals produced by using [hydroxy(tosyloxy)iodo]benzene (HTIB) in fluoroalcohol solvents such as 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP)
