Platinum-catalyzed hydrosilylation - colloid formation as the essential step

The effect of added salts on carbon monoxide adsorption on platinum and palladium hydrosols: an FTIR study

“…Both linear and 2-fold bridging C O have been detected for 'Author to whom correspondence may be addressed. colloidal platinum in dichloromethane (7) and for colloidal palladium in methylcyclohexane media (8). An ab initio SCF study (9) of the Pd-CO chemisorption system has demonstrated that bond weakening in C O due mainly to d,(Pd)-.rr*(CO) backbonding, leads to a calculated frequency (v(C0)) reduction of -72 cm-' with an increase in C-0 bond length of ca.…”

Evidence from infrared ellipsometry for covalent bonding at a polymer/polymer interface with relevance to "lock-up" in pressure-sensitive adhesive laminates

“…Note that the reaction in Figure 4 is apparently occurring at room temperature and in the absence of a catalyst [22,27,28]. In most applications, the formulation would contain a catalyst, which speeds up the rate of SiH hydrolysis and SiH reactions.…”

Synthesis of poly(phosphonosiloxane) and its cyclic monomer via hydrosilylation and phosphonylation of vinylbenzyl chloride

“…This variation of color indicates the formation of colloidal platinum, which was reported to be the key step in the action of the Speier catalyst and Pt(1,5-cyclooctadiene) 2 . 19 The success of hydrosilylation followed by phosphonylation, as delineated in Scheme 1, prompted an attempt to conduct direct hydrosilylation of vinylbenzylphosphonate (VBP) ester using the same platinum-complex catalyst (Scheme 2). This could have been a much better route to proceed, because VBP 20 can be easily prepared and purified without exposing the polymers to the severity of the thermal conditions of the Arbuzov reaction.…”
