-Lithiation driven one-pot synthesis of quinazolines [2 + 2 + 2] cascade annulation of halofluorobenzenes with nitriles.

A one-pot synthesis of 2,4-disubstituted quinazoline derivatives from halofluorobenzenes with nitriles was reported, sequential nucleophilic addition and SAr reaction. The advantages of the present approach are transition metal free, easy to operate, and all the starting materials are commercially available.

Ionically Cross-Linked Polymers as Asymmetric Gel Polymer Electrolytes for Enhanced Cycle Performance of Lithium-Sulfur Batteries.

Two thermoplastic triblock copolymers of poly(ε-caprolactone)-based acidic (PCL-A) and basic (PCL-B) polymers are synthesized by atom transfer radical polymerization. PCL-A and PCL-B are sequentially electrospun on a sulfur electrode and then ionically cross-linked by an acid-base reaction via hot pressing at 70 °C, which is confirmed by infrared (IR) spectroscopy. The cross-linked PCL-A/PCL-B-electrospun sulfur electrode is assembled as a lithium-sulfur battery with an asymmetric gel polymer electrolyte.
