Process for the removal and return of a catalyst to a liquid phase medium

A process for the selective removal of a component from a liquid phase and subsequently returning the component to a liquid phase is disclosed. A novel compound of formula (I) [SUP]-[[L]-[G]]a (I) in which L is a linking group, G is an aryl group having a leaving group LG selected from Cl, Br, I, sulfonate such as triflate, a diazo group, a nitrile, an ester and an alkoxy group and substituent Q is selected from H, NR2, OR, CO2R, F, Cl, NO2 CN and SUP is a support having a plurality of groups -[L]-[G] bound to the support is contacted with the liquid phase to bind the component to the compound I thereby forming a captured component which is separated from and may be returned to the liquid phase. The compound I is especially useful in binding homogeneous catalysts to remove it from a reaction medium and selectively returning the catalyst to the reaction medium at a later stage. The compound is particularly useful for cross-coupling reactions, for example in Suzuki reactions.

PREPARATION METHOD OF FLUORINE-SILICON-CONTAINING POLYPHOSPHATE ESTER AND APPLICATION THEREOF

Disclosed are a fluorine-silicon-containing polyphosphate ester and method for preparation thereof, having a chemical structural formula of:

##STR00001##

wherein R .sub.1 is

##STR00002##

R .sub.2 is

##STR00003##

n=10100. The fluorine-silicon-containing polyphosphate ester of the present invention uses silicon phosphorus and fluorine for improving flame retardancy. Phosphorus catalyzes the system to form a phosphorus-rich carbon layer, performing a protective-layer function and thereby preventing further breakdown of the epoxy resin. The silicon-containing epoxy resin forms a silica-containing carbon layer during the process of combustion, strengthening the carbon-layer structure and further improving the protective function of the carbon-layer. The introduction of elemental fluorine improves the thermal stability of the epoxy resin, thereby improving the flame retardancy performance of the system.
