These catalysts are characterized by a combination of 1D P-31 CP-MAS and 2D P-31-H-1 HETCOR and J-resolved multinuclear solid state NMR experiments. Different binding situations such as singly and multiply coordinated phosphines are identified. Density functional theory (DFT) calculations are performed to corroborate the interpretation of the experimental NMR data, in order to propose a structural model of the heterogenized catalysts. Finally, the catalytic activity of the Si-PB-Ir catalysts is investigated for the hydrogenation of styrene employing para-enriched hydrogen gas.","lang":"eng"}],"volume":231,"date_created":"2026-02-07T15:35:41Z","author":[{"first_name":"Torsten","full_name":"Gutmann, Torsten","id":"118165","last_name":"Gutmann"},{"last_name":"Alkhagani","full_name":"Alkhagani, S.","first_name":"S."},{"first_name":"N.","last_name":"Rothermel","full_name":"Rothermel, N."},{"first_name":"H.
