Hybrid donor extractants are a promising class of compounds for the separation of trivalent actinides and lanthanides. Here, we investigated a series of sterically loaded diphosphonate ligands based on bipyridine (BiPy-PO-iPr and BiPy-PO-cHex) and phenant

Alkyl and cyclic substituted aminophosphonates (AmPs) were synthesized and characterized with various spectroscopic techniques. The molecular structures of diphenyl phenyl aminophosphonate (DPhPhAmP) and diphenyl cyclohexyl aminophosphonate (DPhCyAmP) wer

Two generally applicable systems have been developed for the cross-coupling of P(O)H compounds with Csp2-X and related partners. Palladium catalysis using a ligand/additive combination, typically either xantphos/ethylene glycol or 1,1-bis(diphenylphosphino)ferrocene/1,2- dimethoxyethane, with diisopropylethylamine as the base, proved to be generally useful for the synthesis of numerous P-C containing compounds. Routinely, 2 mol% of catalyst are employed (less than half the amount typically employed in most other literature reports). In most cases, excellent results are obtained with a variety of electrophiles (RX, where R=alkenyl, allyl, alkynyl, etc.). The full account of our studies is disclosed, including tandem hydrophosphinylation/ coupling and coupling/coupling for doubly catalytic phosphorus-carbon bond formation. The methodology compares favorably with any existing literature report. The use of an additive appears to be a generally useful strategy to control the reactivity of phosphinylidene compounds.
