Article Synopsis
- Two new coordination complexes, 1 and 2, were synthesized and characterized using various analytical techniques, revealing their unique structures and compositions.
- In complex 1, manganese ions exhibit a distorted octahedral environment influenced by the ligand and cyanide, while complex 2 features copper ions with a similar structural arrangement.
- Magnetic studies show that 1 has weak antiferromagnetic coupling, whereas 2 displays both ferro- and antiferromagnetic interactions; DFT calculations confirm these findings, indicating strong but weak ferromagnetic behavior in different configurations.
A novel bench-stable V-catalyst [(L)VO](ClO) was synthesized and characterized by X-ray diffraction (XRD) analysis and FT-IR, UV-visible, and EPR spectroscopies, which confirmed its excellent catalytic activity. In application, aldehydes are rapidly converted into their corresponding esters without additives in a one-pot manner using a newly developed catalyst [(L)VO](ClO) and HO as a green oxidant. The developed method is compatible with a broad range of densely substituted aldehydes and allows for the facile preparation of aliphatic, aromatic, and heterocyclic esters, including esters derived from CDOD, methanol, ethanol, -propanol, -butanol, -butyl alcohol, and propargylic alcohol.

Those amino ethers further undergo intramolecular hydroamination via cyclization in the presence of Zn(OTf) as the catalyst and tetrabutylammonium triflate salt as an additive under one-pot two-step reaction conditions. However, for nonracemic examples, ring-opening and cyclization steps were conducted under two-pot conditions.

Inappropriate or sub-optimal positioning of navigation devices increases off-road eye-glance duration and fixation frequency.
Objective: The current research aimed to develop a smartphone holding device to facilitate the mobile-phone's easy mounting on the steering wheel's hub, ensuring the screen's visibility at a comfortable viewing angle in a vertical upright position irrespective of the steering wheel's rotation.
