Yb3+ complexes with two nitrilotriacetic acid molecules were prepared and their compositions were determined as K3[Yb(nta)2(H2O)]*5H2O and Na3[Yb(nta)2]*6H2O by
A practical and scalable synthesis route of acetylphenylboronic acids is described. Bromoacetophenones(compounds 3a, 3b) were ketalized with ethylene glycol and
Complex VO(C12H12N2O2)(C13H10NO2)(C12H12N2O2-2=acetylacetone benzoylhydrozanate, C13H10NO_2=N-phenylbenzohydroxamate) was synthesized and characterized by means
Chitosan, as a kind of natural polymer, has many advantages, such as abundant sources, biological degradation, no secondary contamination and facile modificatio
