Abstract
Alkene-platinum-silyl complexes described by formula (COD)Pt(SiR13−n)2Yn are claimed, where each R1 is independently selected from organic groups, halo atoms, and siloxy groups, each Y is an independently selected divalent bridging group between the silicon atoms bonded to platinum, n is 0, 1, 2, or 3, and COD is 1,5-cyclooctadiene.

Alkene-platinum-silyl complexes described by formula (I)
- (COD)Pt(SiR13−n)2Yn,
- where each R1 is independently selected from organic groups, halo atoms, and siloxy groups, each Y is an independently selected divalent bridging group between the silicon atoms bonded to platinum, n is 0, 1, 2, or 3, and COD is 1,5-cyclooctadiene.
A method of preparing alkene-platinum-silyl complexes described by formula (I)
- (COD)Pt(SiR13−n)2Yn,
- comprising the steps of
- (a1) mixing COD and platinum to form a premix, and
- (b1) adding SiH-containing silanes or siloxanes to the premix, or
- (a2) mixing COD and SiH-containing silanes or siloxanes to form a premix, and
- (b2) adding the premix to platinum,
- where the COD and SiH-containing silanes or siloxanes are added in amounts sufficient to form the complex described by formula (I), where each R1 is independently selected from organic groups, halo atoms, and siloxy groups, Y is a divalent bridging group between the silicon atoms, and COD is 1,5-cyclooctadiene.
A method of hydrosilating a compound having at least one non-aromatic, carbon-carbon multiple bond comprising
- (IA) mixing COD, platinum, and at least one silane or siloxane having at least one non-aromatic, carbon-carbon multiple bond or at least one organic material having at least one non-aromatic, carbon-carbon multiple bond to form a hydrosilation premix-A;
- (IIA) adding to the hydrosilation premix-A at least one silane or siloxane having at least one SiH group,
- such ingredients being added in amounts sufficient to provide at least 3 moles of COD for every one mole of platinum and at least 1 SiH group for each non-aromatic, carbon-carbon multiple bond, where COD is 1,5-cyclooctadiene.
A method of hydrosilating a compound having at least one non-aromatic, carbon-carbon multiple bond comprising
- (IB) mixing COD, at least one silane or siloxane having at least one non-aromatic, carbon-carbon multiple bond or at least one organic material having at least one non-aromatic, carbon-carbon multiple bond, and at least one silane or siloxane having at least one SiH group to form a hydrosilation premix-B;
- (IIB) adding platinum to the hydrosilation premix-B,
- such ingredients being added in amounts sufficient to provide at least 3 moles of COD for every one mole of platinum and at least 1 SiH group for each non-aromatic, carbon-carbon multiple bond, where COD is 1,5-cyclooctadiene.
A method of hydrosilating a compound having at least one non-aromatic, carbon-carbon multiple bond comprising
- (IC) mixing platinum, at least one silane or siloxane having at least one non-aromatic, carbon-carbon multiple bond or at least one organic material having at least one non-aromatic, carbon-carbon multiple bond, and at least one silane or siloxane having at least one SiH group to form a hydrosilation premix-C;
- (IIC) adding COD to the hydrosilation premix-C,
- such ingredients being added in amounts sufficient to provide at least 3 moles of COD for every one mole of platinum and at least 1 SiH group for each non-aromatic, carbon-carbon multiple bond, where COD is 1,5-cyclooctadiene.
