Based on new experimental data, a refined mechanistic picture of carbonyl hydrosilylation with hydrosilanes catalyzed by a cationic rhenium(V) oxo complex introduced by Abu-Omar is presented. A stereochemical analysis employing a silicon-stereogenic hydrosilane as a stereochemical probe revealed that both free silylcarboxonium ions and neutral rhenium(V) hydrides are key intermediates in the catalytic
