A high molecular weight, linear poly(ethylene-co-acrylic acid) (pEAA) was synthesized via the tandem hydrocarboxylation/hydrogenation of cis-poly(butadiene) (cis-pBD). Treatment of cis-pBD (Mn = 160 kDa) with an N,N′-diamidocarbene afforded a polyc

The burgeoning field of polymer mechanochemistry has garnered significant interest in recent years. Mechanochemical transformations are those that are promoted by exogenous forces, and polymer mechanochemistry concentrates on the use of polymer chain

The activation of molecules possessing homonuclear bonds (i.e., X–X, where X = Br, O, S, or C) using a stable N,N′-diamidocarbene (DAC) is described. Exposing bromine to the DAC at 25 °C afforded a substituted tetrahydropyrimidinium salt in good

The specific targeting of covalent bonds in a local, anisotropic fashion using mechanical methods offers useful opportunities to direct chemical reactivity down otherwise prohibitive pathways. Here, we report that embedding the highly inert 1,2,3-tri

Condensation of 9-(4-aminobenzene)-carbazole with 4,4′-difluorobenzophenone afforded a carbazole-functionalized poly(aryl amino ketone) (PAK-Cz). Similarly, a series of poly(ether ether ketone)s (PEEK-Cz) and poly(arylene ether ketone)s (PAEK-Cz) c

A series of 1,3-disubstituted-2-imidazolium carboxylates, an adduct of CO(2) and N-heterocyclic carbenes, were synthesized and characterized using single crystal X-ray, thermogravimetric, IR, and NMR analysis. The TGA analysis of the NHC-CO(2)'s show
