Hydrocarbonylation reactions using alkylphosphine-containing dendrimers based on a polyhedral oligosilsesquioxane core

Metal nanoparticles stabilized by cubic silsesquioxanes for catalytic hydrogenations

“…ColeHamiltonÕs group reported a number of rhodium metallodendrimers based on polyhedral oligomeric silsesquioxanes cores that give much higher region-selectivity than their small molecule analogues in the hydroformylation reactions. The positive dendritic effect was explained by the steric crowding and small arm length inducing eight-membered ring bidentate coordination that enhances the selectivity [38][39][40][41]. In this paper, we report preparation and catalytic hydrogenation of platinum nanoparticles using octa(diacetic aminophenyl) octasilsesquioxanes (OAAPS) as the stabilizer.…”

Synthesis and catalytic activity of the transition metal complex catalysts supported on the branched functionalized polysiloxanes grafted on silica

“…Recently, much attention has been focused on dendrimers and dendrimer-like polymers as macromolecular carriers for homogeneous catalysts (for recent reviews, see [2]). They possess a highly branched structure containing functional sites that act as an anchor for the catalytic species [3][4][5][6][7][8]. The problematic separation of the dendritic catalysts can be overcome by using an ultra filtration technique [9][10][11] or by attaching the branched units to insoluble crosslinked polymers [12,13] or to silica [6,14].…”

Insertion of Iron Decorated Organic–Inorganic Cage-Like Polyhedral Oligomeric Silsesquioxanes between Clay Platelets by Langmuir Schaefer Deposition

“…In recent years, POSS have attracted significant attention because they can be used as templates for fabricating nanostructured materials such as star polymers [14][15][16], catalysts [17,18], and dendrimers [19]. In addition, POSS can be part of "self-healing" high temperature (nano)composites used in coatings [20,21].…”
