An efficient method for synthesizing monofunctionalized derivatives of 1,1,3,3-tetramethyldisiloxane in ionic liquids as recoverable solvents for rhodium catalyst

Functionalized siloxanes, as one of the most important classes of organosilicon compounds, are widely applied in industry. In our studies, we have investigated, the reaction between 1,1,3,3-tetramethyldisiloxane (TMDSO) and 1-octene, using the rhodium cat

An efficient catalytic and solvent-free method for the synthesis of mono-organofunctionalized 1,1,3,3-tetramethyldisiloxane derivatives

Selective mono-functionalization of 1,1,3,3-tetramethyldisiloxane (TMDSO) with olefins via hydrosilylation reaction is reported. On the basis of a study of platinum- and rhodium complexes in the reactions between TMDSO and selected olefins containing C=C bond, it was possible to choose the most efficient catalyst whose application in the solvent-free system led to selective mono-functionalization of the disiloxane reagent and simultaneous formation of only β-regioisomeric products, bearing in their structure functional groups of unique reactivity or physicochemical properties.

Hydrosilylation of alkenes catalyzed by rhodium with polyethylene glycol-based ionic liquids as ligands

A series of polyethylene glycol-functionalized imidazolium ionic liquids has been prepared and characterized. These ionic liquids have been successfully applied in the hydrosilylation of alkenes catalyzed by rhodium complexes. The effects of the length of the polyether chain, the amount of ionic liquid, and the reaction temperature on the catalytic performance of hydrosilylation have been investigated. Furthermore, the catalytic system has been tested for the hydrosilylation of different alkenes with triethoxysilane. The new catalytic system exhibits both excellent catalytic activity and selectivity under low-temperature conditions. The catalyst system could be recycled five times with slightly deactivation.
