The chemistry of superacids has developed in the last two decades into a field of growing
interest and importance. Now available in a new expanded second edition, this definitive …

In the past decades, significant advances have been made on radical Smiles
rearrangement. However, the eventually formed radical intermediates in these reactions are …

Hyperbranched polymers (HBPs) are highly branched macromolecules with 3-dimensional
globular structures, which have unique properties, such as low viscosity, high solubility, and …

This work focuses on the development of high temperature polymer electrolyte membranes
(HT-PEMs) as key materials for HT-PEM fuel cells (HT-PEMFCs). Recognizing the …

The development of anhydrous high-temperature proton-exchange membranes (HT-PEMs)
combining durable high proton conductivity and modest mechanical properties is a huge …

We describe the synthesis of N-sulfonated poly (arylene-oxindole) by metal-free superacid,
denoted IDB, IBP, and IFP by polycondensation of isatin with 1, 4-diphenoxybenzene …

The chemistry of cinnamic acids and related compounds has been studied. In superacid-
catalyzed reactions with arenes, two competing reaction mechanisms are proposed. Both …

Synthesis of processable, aromatic pyridine-containing polymers has always been a great
challenge. Here, we report for the first time a robust, low-cost synthesis of well defined, high …

Trifluoromethyl-substituted superelectrophiles were generated in superacid (CF3SO3H),
and their chemistry was examined. The strong electron-withdrawing properties of the …

The silver (I) and iodine (I) complexes of the 2-substituted pyridines 2-(diphenylmethyl)
pyridine (1) and 2-(1, 1-diphenylethyl) pyridine (2), along with their potential protonated side …
