QSAR studies and antimicrobial potential of 1,3-thiazolylphosphonium salts

open access: yes, 2016
The regression QSAR models were built to predict the antimicrobial activity of new thiazole derivatives. Compounds with high predicting activity were synthesized and evaluated against Gram-positive and Gram-negative bacteria and fungi.

Scalable Synthesis of Highly Reactive 1,3-Diamino Dienes from Vinamidinium Salts and Their Use in Diels–Alder Reactions

open access: yes, 2016
A practical and chromatography-free synthesis of vinamidinium salts and their use as diene precursors in Diels–Alder reactions is reported. Additionally, 1,3-dipyrrolidino-1,3-butadiene was shown to be significantly more reactive than Rawal’s diene in a ...

The synthesis and redox properties of new 1,3-dithiole systems [PDF]

open access: yes, 1992
The theory of conductivity in organic metals and a review of organic π-electron donors is introduced in Chapter One, outlining some of die many variations that have been made to the tetrathiafulvalene (TTF) molecule, the donor component in the first true

SYNTHESIS OF 1,3-DIALKYLPERHYDROBENZIMIDAZOLINIUM SALTS AND THEIR CATALYTIC PROPERTIES IN HECK REACTIONS

open access: yes, 2013
Novel eight 1,3-dialkylperhydrobenzimidazolinium chloride salts 3a-h were prepared as precursors of N-heterocyclic carbenes by reacting N,N'-dialkylcyclohexanediamine, triethyl orthoformate and ammonium chloride.

Synthesis and crystal structures of non-symmetric 1,3-di(alkyloxy)imidazolium salts

open access: yes, 2017
A series of non-symmetric 1,3-di(alkyloxy)imidazolium salts were synthesized by stepwise alkylation of 1-hydroxyimidazole-3-oxide. The quaternary salts were subsequently functionalized by bromination in 2-position.

Ultrasound-assisted synthesis of functionalized 1,3-enynes by palladium-catalyzed cross-coupling reaction of alpha-styrylbutyltelluride with alkynyltrifluoroborate salts

open access: yes, 2008
An ultrasound-assisted synthesis of functionalized 1,3-enyne scaffolds is described and illustrated by palladium-catalyzed cross-coupling of potassium alkynyltrifluoroborate salts and alpha-styrylbutyltellurides.

Synthesis of highly stabilized ylides from N-[2-(1,3-benzazolylmethyl)]pyridinium salts

open access: yes, 1990
A series of new stable ylides has been synthesized by the reaction of N-[2-(1,3-benzazolylmethyl)]-pyridinium salts with electrophiles such as carbon disulphide, isothiocyanate derivatives, phenylisocyanate and benzoyl chloride in a two-phase system ...
