<p>Catalyst (A) for dehydrogenative condensation of -Si(H)-units containing polyorganosiloxane compounds (I) (where catalytic system comprising at least a boron containing compounds and at least a synergistically effective compounds, salts or complexes, with cation of the group by elements of 4, 6, 7th and 8th next to group and 4th main group are used as (A)), is new. Catalyst (A) for dehydrogenative condensation of -Si(H)-units containing polyorganosiloxane compounds of formula (I) (where catalytic system comprising at least a boron containing compounds and at least a synergistically effective compounds, salts or complexes, with cation of the group by elements of 4, 6, 7th and 8th next to group and 4th main group are used as (A)), is new. R : alkyl-, aryl-, alkylaryl- or arylalkyl with 1-20C (preferably 1-10C), 1-20C haloalkyl, siloxy or triorganosiloxy; Ra, Rb : H or R; x : 0-300; and y : 0-100. Provided that at least Si-atom is bound to hydrogen atom in the molecule, with at least an alcohol (aromatic, fluorinated or perfluorinated, (meth)acrylated, aliphatic aromatic, optionally other functions of carrying mono- or polyalcohols, polyether mono- or polyether polyalcohols, aminoalcohols (N-alkyl-, arylamino-EO-, -PO-alcohols), N-alkyl and/or arylaminoalcohols. An independent claim is also included for a method of partially or completely converting one or more Si(H) units containing (I), comprising partially or completely replacing hydrogen from the Si(H)(R)-O- unit of (I) by alcohol residues of the used alcohol, optionally under inert gas and solvents at appropriate temperature for the catalytic system at 70-150[deg]C.
