Journal ArticleDOI
1H NMR Spectroscopic Investigation of the Mechanism of 2-Substituted-2-Oxazoline Ring Formation and of the Hydrolysis of the Corresponding Oxazolinium Salts
Marian N. Holerca,Virgil Percec +1 more
TL;DR: The mechanism of neutral and base-assisted hydrolysis of 2-substituted-2-oxazolinium salts by the nucleophilic attack at the C2 rather than the C5 position of the ring was elucidated in this paper.
Journal ArticleDOI
Functional polymers and sequential copolymers by phase transfer catalysis, 21. Thermotropic aromatic poly(ether sulfone)s: A new class of thermotropic aromatic main‐chain liquid crystalline polymers
Timothy D. Shaffer,Virgil Percec +1 more
TL;DR: In this paper, phase transfer catalyzed (PTC) polyetherification of bis(4-chloro-3-nitrophenyl) sulfone with mesogenic aromatic diols is described.
Journal ArticleDOI
