Benign coupling of reactions and separations with reversible ionic liquids

Reversible ionic liquids are a novel class of solvents that combine an effective medium where reactions occur with a 'built-in' separation ability for facile recovery of the products and catalysts, making the solvent available for recycle. We report the utility of these solvents in a number of reactions (Claisen-Schmidt condensation, Heck C-C coupling, and CO2 capture) and discuss the effectiveness of the separation. We also provide insight into the challenges and limitations of using these unique solvent systems to couple reactions and separations.

Method for the preparation and use of bis (alkoxysilylorgano)-dicarboxylates

A method for preparing a bis(alkoxysilylorgano) dicarboxylate includes reacting a haloorganoalkoxysilane, a dimetal salt of a dicarboxyl functional compound, and a phase transfer catalyst. A quaternary iminium compound of a polyaza,polycycloalkene is useful as the phase transfer catalyst. The product may be a bis(alkoxysilylalkyl) fumarate, which is useful as a coupling agent in rubber compositions for tire applications.

ESTER-FUNCTIONAL SILANES AND THE PREPARATION AND USE THEREOF;AND USE OF IMINIUM COMPOUNDS AS PHASE TRANSFER CATALYSTS

A method for producing a reaction product comprising an ester-functional silane, the method comprising: i) reacting a composition comprising: a) a haloorganosilane, b) a metal salt of a carboxy-functional compound, c) a phase transfer catalyst comprising a bicyclic amidine, an iminium compound, or a mixture thereof, provided that the iminium compound is not an acyclic guanidinium compound or pyridinium compound, and d) a co-catalyst, provided that the co-catalyst is optional when the phase transfer catalyst comprises the iminium compound.

Naphthalene anti-psoriatic agents

Psoriasis in mammals is relieved by topically administering naphthalenes of the formula: STR1 wherein: R1 and R2 are the same and are lower alkoxy or optionally substituted phenoxy, R3 is lower alkyl, lower alkoxy, or halo
