Methods of producing α,β-unsaturated carboxylic acid salt are described. A method can include reacting an alkene and carbon dioxide with a composition that includes a carboxylation catalyst, an organic base that is solubilized in the composition, and an inorganic base that is not solubilized in the composition, under reaction conditions suitable to produce an inorganic base salt of an α,β-unsaturated carboxylic acid. The organic base can have a first pKa and the inorganic base has a second pKa that is greater than the first pKa.

The reactions between [RuCl2(PPh3)3] and half or one equivalent of a diazadiene (dad) give respectively molecular and ionic binuclear triply chloro-bridged complexes, [Ru2Cl4(PPh3)3(dad)] and [Ru2Cl3(PPh3)2(dad)2]Cl which can also be obtained as its B Ph4 salt. The compound [RuH(Cl)(PPh3)3] reacts with diazadienes to produce [RuH(Cl)(PPh3)2(dad)], which disproportionates in polar solvents to give a

A halogenated aromatic monomer-metal complex useful for preparing a polymer for electronic devices such as a light-emitting diode (LED) device is described. The aromatic monomer-metal complex is designed to include a linking group that disrupts conjugation, thereby advantageously reducing or preventing electron delocalization between the aromatic monomer fragment and the metal complex fragment. Disruption of conjugation is often desirable to preserve the phosphorescent emission properties of the metal complex in a polymer formed from the aromatic monomer-metal complex. The resultant conjugated electroluminescent polymer has precisely controlled metal complexation and electronic properties that are substantially or completely independent of those of the polymer backbone.

An efficient and versatile synthesis of novel exo-imidazolidin-2-one dienes is described. This involves the base-assisted condensation/cyclization cascade reaction of the monoimino derivatives of diacetyl with a series of isocyanates. This methodology enables preparation of symmetrical dienes, as long as the substrates have the same N substituent. Moreover, use of different N-substituted starting materials
