The first general open-flask synthesis of amine-boranes with inexpensive and readily available reagents, such as sodium borohydride, sodium bicarbonate, water, and the desired amines is described. Even amines bearing borane-reactive functionalities, such as alkene, alkyne, hydroxyl, thiol, ester, amide, nitrile, and nitro are well tolerated. Some of these novel amine-boranes represent stable mo...

Background: Focused electron beam induced deposition (FEBID) allows for the deposition of free standing material within nanometre sizes. The improvement of the technique needs a combination of new precursors and optimized irradiation strategies to achieve a controlled fragmentation of the precursor for leaving deposited material of desired composition. Here a new class of copper precursors is s...

We investigate the impact of ligands on the morphology, electronic structure, and optical response of the Cd(33)Se(33) cluster, which overlaps in size with the smallest synthesized CdSe nanocrystal quantum dots (QDs). Our density functional theory calculations demonstrate significant surface reorganization for both the bare cluster and the cluster capped with amine or phosphine oxide model liga...

To tune the lanthanide luminescence in related molecular structures, we synthesized and characterized a series of lanthanide complexes with imidazole-based ligands: two tripodal ligands, tris{[2-{(1-methylimidazol-2-yl)methylidene}amino]ethyl}amine (Me(3)L), and tris{[2-{(imidazol-4-yl)methylidene}amino]ethyl}amine (H(3)L), and the dipodal ligand bis{[2-{(imidazol-4-yl)methylidene}amino]ethyl}a...

Based on previously highlighted structural features, the development of highly selective 5-HT1A receptor inhibitors is closely linked to incorporation a 4-alkyl-1-arylpiperazine scaffold them. In this paper, we present synthesis two new compounds bearing 2-MeO-Ph-piperazine moiety via three carbon atom linker amine group 1-adamantanamine and memantine, respectively. Both were tested for their b...

In this article, we describe the process of binding riboflavin to a simple tetradents ligand substituted in α- position from TPAs types, by reacting bromotetraacetate with TPA one pyridine rings nitrile group and two other halogen atoms. This type ligands showed very important properties for activation transfer oxygen substrate presence iron salt. After were obtained, was reduced an amine where...

The first examples of Group 1 metal complexes of tris(2-dimethylaminoethyl)amine (Me(6)TREN) are reported including monomeric sodium complexes containing eta(4)-bound ligands, suggesting their potential use in alkali-metal-mediated synthetic applications.

We have introduced a selective synthesis of tertiary amines using alkyl halide and ammonium salts as the amine sources in water. This green process has outstanding superiorities, such as being eco-friendly, possessing ammonium salts, and using water as a green solvent in the absence of organic ligands or catalysts. It is worth mentioning that the presence of t-Butyl alcohol and potassi...

The main objective in this paper is to report stability constant values of transition metals like Cu (II), Ni(II), co(II) and Zn(II) with schiff's base ligand. Schiff's ligands were synthesized by the condensation reaction -Naphtaldehyde 7-Hydroxy naphthalene 2-amine. Stability for given ligand found be order cu(II)>Ni(II), co(II)>Zn(II).
