South-western Australia harbours a global biodiversity hotspot on the world's most phosphorus (P)-impoverished soils. The greatest biodiversity occurs on the most severely nutrient-impoverished soils, where non-mycorrhizal species are a prominent component of the flora. Mycorrhizal species dominate where soils contain slightly more phosphorus. In addition to habitat loss and dryland salinity, a...

Abstract The ascomycete fungus Microdochium nivale is one of the most damaging pathogens cool season turfgrass. Prevention and recovery from infection costly to many sports facilities each year. In recent years, use chemical plant protectants has been restricted turfgrass managers have increasingly sought alternative measures for disease control. phosphite shown be effective in reducing M. symp...

Two new metal phosphite-oxalates, CN3H6·Co(H2PO3)(C2O4) (1) and (CN3H6)2·Mn2.5(HPO3)(C2O4)2.5(H2O)·H2O (2), have been prepared under solvent-free conditions. The two open-framework compounds have diamondoid and pillared-layered structures, respectively. Their photoluminescence and magnetic properties were also investigated.

Chloromethylgold(I) complexes of phosphine, phosphite, and N-heterocyclic carbene ligands are easily synthesized by reaction of trimethylsilyldiazomethane with the corresponding gold chloride precursors. Activation of these gold(I) carbenoids with a variety of chloride scavengers promotes reactivity typical of metallocarbenes in solution, namely homocoupling to ethylene, olefin cyclopropanation...

An efficient synthesis of a Pk trisaccharide with a functionalized side arm at the reducing end for conjugation to other molecules is presented. Construction of the Pk trisaccharide with a high alpha-selectivity was achieved in high yield by coupling a reactive galactosyl phosphite donor with a lactosyl acceptor.

A highly practical, catalytic enantioselective cyclic phosphite addition to aldehydes and ketones was developed. The reaction rate of the asymmetric hydrophosphonylation was significantly enhanced by the addition of silver carbonate. Particularly, significant improvement has been achieved on the asymmetric hydrophosphonylation of unactivated ketones, giving quaternary α-hydroxy phosphonates wit...
