Sentence examples for first coordinates to from inspiring English sources

In this tandem reaction the iridium catalyst is required for both conversions: it acts as the Lewis acid in the Nazarov cyclization and in the next step the nitro group of nitrostyrene first coordinates to iridium in a ligand exchange with the carbonyl ester oxygen atom before the actual Michael addition takes place to the opposite face of the R-group.

Based on our results, oxygen first coordinates to the ferric center at a vacant site generated by partial dissociation of the catecholate substrate, which is simultaneously oxidized to a semiquinone by oxygen, with the iron center acting as an electron buffer.

A structural model has been proposed for the function of human homotrimeric hCtr1 in which Cu(I) first coordinates to the methionine-rich motif in the hCtr1 extracellular amino (N -terminus aN -terminusonserved methionine residue upstreandof thenfirst transmembrane domain is essential for conservedort [ 33, 34].

The RAFT agent (1), 4-cyano-4- dodecylsulfanylthiocarbonylsulfanyl pentanoic acid, with an available carboxyl group was first coordinated to the n-TiO2 surface, with the SC(SC12H25) moiety subsequently used for RAFT polymerization of MMA to form the n-TiO2/PMMA nanocomposites.

Electrophilic Pt II) complexes efficiently initiate the cation olefin reaction by first coordinating to the alkene with selection rules that favor less substituted alkenes over more substituted alkenes.

In the latter case the base is absent and the palladium apparently prefers to first coordinate to the C=C bond; the resulting species then undergoes a traditional attack from the opposite face as in any classical electrophilic addition.

Here, the initial PdCl2/CuCl2 complex 32-Cu first coordinates ethylene to produce 6-Cu (upon a loss of Cl−), which then can be attacked by water either at Pd or at the carbon via transition states 33-Cu and 34-Cu, respectively, of which the latter is lower in energy by 4.0 kcal mol−1, indicating that the anti-pathway is preferred.

where the indices 55 64 for the first coordinate correspond to the numerical characters 0 9 and the indices 55 64 for the second coordinate indicate the last ten locations on the keyboard.

High-spin heme iron III) species with O atom axial coordination typically exhibit ν3 modes that are intense relative to the ν4 and ν2 modes, and the high ν3/ν4, ν2 intensity ratio observed in the RFQ-RR spectra of the millisecond intermediate formed in wt HasAp supported the notion that Y75 is the first coordinating ligand to the iron III).

Next, we use the same notations as those in Hassard et al. [20], and we first compute the coordinates to describe the center manifold (C_{0}) at (upsilon=0).

Cavalieri first used polar coordinates to solve a problem relating to the area within an Archimedean spiral.
