文摘

The cover picture shows a new synthetic route for the direct conversion of sodium phosphinate (NaH₂PO₂·H₂O) to diorganophosphinates and their corresponding acids by using palladium catalysis. Diorganophosphinates and their derivatives are relevant in many fields of application: from flame retardants to solar cells and from ligands for catalysis to pharmaceutical applications and metal extraction. They can also be interesting intermediates in the synthesis of other P-derivatives. The new synthetic route eliminates the need for chlorinated precursors, such as PCl₃, or intermediate alkyl- or ammoniumphosphinates. Details are discussed in the Communication by B.-J. Deelman et al. on page 434 ff (DOI: joc.201601222/abstract" title="Link to external resource: http://onlinelibrary.wiley.com/doi/10.1002/ejoc.201601222/abstract" target="_blank">10.1002/ejoc.201601222).
