Moreover, the use of NEt3 for deprotonating BTC generates cationic NEt3+ species; we noted from the literature[ 27] the propensity of NEt3 to coordinate with Cu II) in the presence of coordinating organic ligands.
Stereochemistry of the intramolecular alkoxypalladation-β-elimination cascade (reaction B ; entries 5 7) can be controlled by the anion: thus, with PdCl2, that is, with strongly coordinating chlorides, especially in the presence of additional LiCl, the potential coordination of the participating alcohol group to Pd is disfavored and the reaction proceeds as an anti-addition (entry 5).
Both Mg2+ and Mn2+ are coordinated by D70 and E96 in the absence of bound substrate and coordinated by E96 alone in the presence of DNA product in crystal structures.
"Thousands of civilians have been killed in Yemen, including a large number by the Saudi air force and they've done that using British-built planes, with pilots who are trained by British instructors, dropping British-made bombs, who are coordinated by the Saudis in the presence of British military advisors," Mr Robertson said during Prime Minister's Questions.
Instability of 68Ga-labeled peptides was only observed if they were coordinated with a DOTA in the presence of excess Cu2+.
In addition, we design a new contract and coordinate the supply chain in the presence of the agents' social preferences.
The enhancement in ECL by zinc ions is attributed to the direct coordinate interactions with ligand monolayer in the presence of HEPES and confirmed by similar enhancement in the near IR photoluminescence.
The conformation of these loops is determined by the presence of calcium and transition metal ions coordinated in the protein structure [ 17– 17].
Polar solvents, capable of dissolving the inorganic lead and ammonium halide salts, are injected into a nonpolar "poor" solvent in the presence of coordinating ligands to stabilize the newly formed particles.
This result indicated that Bi-rich surfaces of Bi2S3 quantum dots were produced, which is consistent with metal-chalcogenide nanocrystals synthesized in the presence of coordinating ligands bound covalently to cations [7].
