Benzylicalcohols cross-couple directly with concentrated H(3)PO(2) using Pd/xantphos (1 or 2 mol-%). Depending on the substrate, DMF at 110 degrees C, or t-AmOH at reflux with a Dean-Stark trap, can be used. A broad range of benzylicalcohols reacted successfully in moderate to good yields. The preparation of other organophosphorus compounds (phosphinic and phosphonic acids) is also demonstrated.Asymmetric

Elemental phosphorus (red or white) reacts with alkyl bromides at 60-62 degrees C in the phase-transfer catalytic system KOH/H2O/PhMe/Et3BnNCl to afford alkyl-H-phosphinic acids in up to 47% yield.
