Complex 1 has proven to be an effective catalyst precursor for the reaction of styrene derivatives with hydrosilanes in CD2Cl2. However, under catalytic conditions complex 2 decomposes. The performance of the 1‐catalyzed reaction of styrene with hydrosilanes strongly depends on the nature of the silane, the best catalytic performance was achieved using HSiMe2Ph. Theoretical and 1H NMR studies indicate that the hemilabile nature of the NSi ligand is key to understanding the catalytic activity of compound 1. info:eu-repo/grantAgreement/ES/DGA/E42-23R info:eu-repo/grantAgreement/ES/MICINN/PID2021-122763NB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2021-126212OB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2023-148113OB-I00 info:eu-repo/grantAgreement/ES/UZ/JIUZ-2023-CIE-10 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Padilla, Marina Universidad de Zaragoza Martínez de Morentin, Aitor (orcid)0000-0002-7063-1292 García-Orduña, Pilar Huertos, Miguel A.
