Abstract
Nanoparticles that can be used as hydrosilylation and dehydrogenative silylation catalysts. The nanoparticles have at least one transition metal with an oxidation state of 0, chosen from the metals of columns 8, 9 and 10 of the periodic table, and at least one carbonyl ligand, preferably a silicide.
Claims11
Nanoparticles having an average diameter, determined by transmission electron microscopy, less than or equal to 50 nm, and comprising:
- at least one transition metal with an oxidation state of 0, chosen from the metals of columns 8, 9 and 10 of the periodic table,
- at least one carbonyl ligand, and
- at least one silicide wherein said silicide is chosen from compounds having formula (I):
- YpZ4qSiHr (I)
- wherein:
- the symbol(s) Y, identical or different, represent a metal chosen from the metals of columns 8, 9 and 10 of the periodic table;
- the symbol(s) Z4, identical or different, represent an alkyl group having from 1 to 18 carbon atoms inclusive;
- p=1, 2 or 3;
- q=1, 2 or 3;
- r=0, 1 or 2;
- p+q+r=4.
