A New bis(rhodamine)-Based Fluorescent Chemosensor for Fe3+
A new bis(rhodamine)-based fluorescent probe 4 was synthesized, and it exhibited high selectivity for Fe3+ over other commonly coexistent metal ions in both 50% ethanol and TrisâHCl buffer. Upon the addition of Fe3+, the spirocyclic ring of 4 was opened and a significant enhancement of visible color and fluorescence in the range of 500â600Â nm was observed
Two new species of Cardicola (Trematoda: Aporocotylidae) from the damselfish Abudefduf whitleyi (Perciformes: Pomacentridae) and the triggerfish Sufflamen chrysopterum (Tetraodontiformes: Balistidae)
A Homogeneous Chiral Manganese(III)-Salphe Catalyst for Enantioselective Epoxidation of Olefins
A new chiral Mn(III)-Salphe catalyst was synthesized from natural amino acid (R)-phenylalanine and 3,5-di-tert-butyl-hydroxybenzaldehyde and applied to the asymmetric epoxidations of unfunctionalized olefins in ionic liquids. Satisfactory enantioselectivities (79%</p
