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

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 catalyst immobilized in six phosphonium-based ionic liquids differing in the structure of cation and anion. Studies have shown high potential for using ionic liquids to create biphasic system with reactants, where IL/catalyst phase can be separated and reused in subsequent reaction cycles allowing, in this way, for efficient and highly selective monofunctionalization of TMDSO with reuse of the same portion of catalyst up to 20 times in comparison to conventional homogenous reaction.
