Synthesis of Aliphatic Bis(Thioureas) [PDF]

open access: yes, 1991
The synthesis of aliphatic bifunctional thioureas have been attempted using several nucleophilic displacement reactions. The first method involved treatment of an aliphatic diamine with ammonium thiocyanate, under two different sets of reaction ...

One-Pot Synthesis of 5-Arylidene-2-Imino-4-Thiazolidinones under Microwave Irradiation

open access: yesMolecules, 2006
A rapid and easy solvent free one-pot synthesis of 5-arylidene-2-imino-4- thiazolidinones by condensation of the thioureas with chloroacetic acid and an aldehyde under microwave-irradiation is described.

Untersuchungen zum Reaktionsverhalten von N,N-disubstituierten Thioharnstoffen gegenüber Dicyanimid (DCI)

open access: yesCHIMIA, 1974
N,N-disubstituted thioureas react with dicyanimide in a simple reaction to form derivatives of the 4H-1.3.5-thiadiazine. The N,N-dimethyl-, N,N-diethyl- and N,N-di-n-propyl-thiourea react under formation of derivatives of S, S'-bis-guanyl ...

Preorganized bis-thioureas as powerful anion carriers: chloride transport by single molecules in large unilamellar vesicles.

open access: yesJournal of the American Chemical Society, 2014
Transmembrane anion carriers (anionophores) have potential in biological research and medicine, provided high activities can be obtained. There is particular interest in treating cystic fibrosis (CF), a genetic illness caused by deficient anion transport.

Catalyst-Free Synthesis of Polysubstituted 5-Acylamino-1,3-Thiazoles via Hantzsch Cyclization of α-Chloroglycinates

open access: yesMolecules, 2019
A catalyst-free heterocyclization reaction of α-chloroglycinates with thiobenzamides or thioureas leading to 2,4-disubstituted-5-acylamino-1,3-thiazoles has been developed.

Carbon Quantum Dots Meet Perovskite Solar Cells: A Review of Multifunctional Synergies

open access: yesCarbon Energy, EarlyView.
This review highlights the multifunctional role of carbon dots in perovskite solar cells. Their applications as additives and interfacial modifiers are discussed in terms of crystallization control, defect passivation, energy‐level alignment, and environmental stability.

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

open access: yesCarbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.

Flipping the Card With Enantiodivergent Organocatalysis

open access: yesChemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...
