摘要： The invention concerns an improved method for preparing catalysts for hydrosilylation reactions of compounds with ethylene or acetylene unsaturation (for example olefins or acetylene derivatives), in particular but not exclusively those involving polyorganosiloxanes (POS) bearing Si-H units and POS bearing Si-(ethylene or acetylene unsaturation) units. Said preparation corresponds to the following synthesis (I), wherein: A = B = carbon; T1, T2 = cyclohexyl, t-butyl or methyl; T3, T4 = H; DVTMS = divinyltetramethylsiloxane; t-BuOK = potassium tert-butylate; T.A = room temperature. The invention is characterised in that it consists in carrying out said synthesis in a single step by bringing together salt (III) above, Karstedt (IV) in the presence of a solvent (V) (THF) and a base (VI) (t-BuOK) at room temperature.

摘要： The invention relates to a silicon composition which can be crosslinked by means of dehydrogenative condensation between reactive units =SiH and =SiOH, using a catalytic complex of iridium. The aforementioned catalytic complex of iridium can be obtained by reacting: (i) a complex of iridium having formula (I): (IrΣΣ'2)n, wherein: A/ n is 1 or 2 and, if n is 1, S is a radical ligand LX with 3 electrons, but, if n is 2, S is a radical ligand X with 1 electron which acts like 3-electron ligand LX with the two iridium atoms; and B/ S', which may be identical or different, but are preferably identical, each represent a ligand L with 2 electrons; and (ii) a ligand Sd which is selected from R2S, R2O, NR3, carbenes and organophosphorous ligands.

摘要： The invention relates to a method for preparing polyorganosiloxane (POS) by a ring(s)-opening polymerisation and/or linear, non-linear or cyclic POS redistribution in the presence of a nucleophile carbene The aim of said invention is to offer an improved method for preparing POS by means of an efficient catalytic system at a low temperature, wherein the initial (for example of D4) efficiency of the POS conversion is substentially increased in comparison with a preceding state of the art in such a way that the initial POS (for example of D4) residual content is less than before. For this purpose, the following components are used: 500g of POS and/or POScy (i.e. D4), 0-10 g, preferably 0.5-2 g of chain stopper (i.e. M2), 0-10g, preferably 0.01-1g of a carbene salt precursor (formulas (III) or (III'), i.e. imidazolium salt), 0-10g, preferably 0.01-0.5g of base (i.e. t-Bu-OK) and 0.1-10 ml of a solvent (i.e.THF).
