The cover picture shows the efficient reduction of triphenylphosphine oxide to triphenylphosphine via the simultaneous action of Brønsted acids and silanes, depicted as a highly professional robotic arm that withdraws the oxygen atom from the phosphine oxide. In this study, we report that the thermally stable HOTf adduct of triphenylphosphine oxide is efficiently converted into triphenylphosphine at 100°C in the presence of readily available hydrosiloxanes. Under the same reaction conditions, also Ph 3 POSiMe 2 H + OTf – selectively affords triphenylphosphine indicating that silylated phosphine oxides are likely intermediates in this process. Details are discussed in the article by Tetiana Krachko et al. on page 916 ff .
