ADMET Polymerization: Greener Method for Synthesis of End-Functionalized Poly(Arylene Vinylene)s

“Geber’s Method” and “Greener” Synthesis of Sulfuric Acid

The release of sulfur dioxide (SO2) into the atmosphere as a result of man’s domestic and industrial activities is a great environmental concern. A significant source of SO2 release into the atmosphere is industrial manufacture of sulfuric acid. A synthetic procedure that is linked with the medieval alchemist named Geber is introduced as a method to be considered for “greener” synthesis of sulf...

Synthesis and facile end‐group quantification of functionalized PEG azides

Azido-functionalized poly(ethylene glycol) (PEG) derivatives are finding ever-increasing applications in the areas of conjugation chemistry and targeted drug delivery by their judicious incorporation into nanoparticle-forming polymeric systems. Quantification of azide incorporation into such PEG polymers is essential to their effective use. 1H Nuclear Magnetic Resonance (NMR) analysis offers th...

Acyclic Diene Metathesis (ADMET) Polymerization for Precise Synthesis of Defect-Free Conjugated Polymers with Well-Defined Chain Ends

This accounts introduces unique characteristics by adopting the acyclic diene metathesis (ADMET) polymerization for synthesis of conjugated polymers, poly(arylene vinylene)s, known as promising molecular electronics. The method is more suitable than the other methods in terms of atom efficiency affording defect-free, stereo-regular (exclusive trans) polymers with well-defined chain ends; the re...

Synthesis of Functionalized Coumarins

The synthesis of functionalized 2-oxo-2H-coumarin derivatives has been studied by a one-pot reaction of o-hydroxybenzaldehyde, ethyl 2-bromoacetate and triphenylphosphine in the presence of catalytic amount of triethyl amine in EtOAc, water or under solvent free conditions. We have found the best results obtained under solvent free condition.
