Multicomponent Combinatorial Polymerization via the Biginelli Reaction

A multicomponent combinatorial polymerization method has been exploited as a new intersection between combinatorial chemistry, polymer chemistry, and organic chemistry. The tricomponent Biginelli reaction has been employed as a model multicomponent reaction (MCR) to efficiently prepare a library of polycondensates with continuously changed chain structure but different physical properties. The naturally increased reaction modules (monomers) directly doubled the number of polymers in the library, effectively improving the efficiency of polymer preparation. The glass transition temperatures (Tg) of those homologous polymers have been mapped for the first time to predict the Tg values of absent polymer homologues with good to excellent accuracy. Meanwhile, the Tg maps have also been used to reveal the regular change in Tg according to the polymer structure (linking group, monomer chain length, etc.), initially suggesting the academic significance of the multicomponent combinatorial polymerization system. We believe that the current research paves a straightforward way to synthesize new libraries of polymers via MCRs and might prompt the broader study of MCRs in interdisciplinary fields.

Synthesis and thermal analysis of crosslinked imidazolium-containing polyester networks prepared by Michael addition polymerization

Several new covalently crosslinked imidazolium-containing polyester networks were prepared by Michael addition polymerization to probe how ionic functionality might affect thermal properties such as glass transition temperature (Tg) and thermal decomposition (Td5%). A structure-activity relationship was investigated involving a variation of the methylene spacer and the counteranion of the acetoacetate precursors. Analysis of Tg by differential scanning calorimetry (DSC) indicated that a longer methylene spacer (n = 6 versus 2) resulted in lower Tg values due to increased chain mobility. It was also discovered that the larger the counteranion, the lower the Tg(Br->NO3 -≈BF4->CF3CO2 ->NTf2-). Thermogravimetric analysis (TGA) indicated that the thermal stability of the polyesters was inversely related to the basicity of the counteranion used, following the trend: (NTf 2->BF4->N3 ->Br-). The exception was the trifluoroacetate- containing polyester, which exhibited the lowest thermal stability.

Highly selective intra- and intermolecular coupling reactions of diazo compounds to form cis-alkenes using a ruthenium porphyrin catalyst

[Ru(2,6-Cl2TPP)(CO)] catalyzed intramolecular coupling reactions of bisdiazoacetates and intermolecular coupling reactions of monodiazoacetates to afford the coupling products in up to 76% and 93% yields, respectively. Only the cis isomers were obtained from the reactions. Employing such a ruthenium-catalyzed coupling reaction of a diazo compound as a key step allowed the synthesis of Patulolide B in 67% yield with a ratio of >40:1 against its trans isomer.

Liquid oligomers containing acrylate unsaturation

The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from >/=1:1 to >/=13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
