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.

Palladium-catalyzed cross-coupling of H-phosphinate esters with chloroarenes
Deal, Eric L.,Petit, Christelle,Montchamp, Jean-Luc
supporting information; experimental part, p. 3270 - 3273 (2011/08/03)
The palladium-catalyzed cross-coupling reaction between H-phosphinate esters and chloroarenes or chloroheteroarenes is described. This reaction is the first general metal-catalyzed phosphorus-carbon bond-forming reaction between a phosphorus nucleophile and chloroarenes.
