Neopentylglycolborylation of ortho-Substituted Aryl Halides Catalyzed by NiCl2-Based Mixed-Ligand Systems
Costel Moldoveanu,Daniela A. Wilson,Christopher J. Wilson,Pawaret Leowanawat,Ana-Maria Resmerita,Chi Liu,Brad M. Rosen,Virgil Percec +7 more
TL;DR: NiCl(2)-based mixed-ligand systems were shown to be very effective catalysts for the neopentylglycolborylation of aryl iodides, bromides, and chlorides bearing electron-rich and electron-deficient ortho-substituents.
Journal ArticleDOI
Polyarylacetylenes: Structure and properties
TL;DR: In this paper, the structure and properties of polyarylacetylenes were investigated and the results on the polypentadeuterophenylacetylacetylene isomers were presented.
Journal ArticleDOI
Liquid-crystalline polyethers based on conformational isomerism. 18. Polyethers based on a combined mesogenic unit containing rigid and flexible groups: 1-(4-hydroxy-4'-biphenyl)-2-(4-hydroxyphenyl)butane
Virgil Percec,Masaya Kawasumi +1 more
TL;DR: In this article, the phase behavior of TPBX copolymers was analyzed by analyzing the various trends of the dependences of the glass transition, nematic-isotropic, isotropic-nematic, melting and crystallization temperatures as a function of X.
Journal ArticleDOI
Liquid-crystalline polymers containing heterocycloalkane mesogenic groups. 5. Synthesis of biphasic chiral smectic polysiloxanes containing 2,5-disubstituted-1,3-dioxane- and 2,5-disubstituted-1,3,2-dioxaborinane-based mesogenic groups
Bruce Hahn,Virgil Percec +1 more
TL;DR: In this paper, the synthesis of side-chain liquid crystalline polysiloxanes containing chiral mesogenic side-groups is presented, which are biphasic systems resembling the behavior of phase separated graft copolymers, i.e., they exhibit a micro-phase separated morphology containing main-chain and sidechain domains.
Journal ArticleDOI
Acid dissolution of copper oxides as a method for the activation of Cu(0) wire catalyst for SET‐LRP
Nga H. Nguyen,Virgil Percec +1 more
TL;DR: In this paper, the acid dissolution of copper oxides as a methodology for the activation of Cu(0) wire used as catalyst in single-electron transfer living radical polymerization (SET-LRP) was reported.
