Sentence examples for introduced bromine from inspiring English sources
The advantages and drawbacks of the studied reaction conditions, the obtained degree of bromination as analyzed by X-ray photoelectron spectroscopy (XPS) and the amount of introduced bromine that can be substituted by a nucleophile are presented and discussed.
Now we focused our attention on positions 5 and 6 of the central benzimidazole and introduced bromine (3b 5/6, 3c), phenylcarbonyl (3d 5/6), hydroxy phenyl)methyl (3g 5/6), hydroxymethyl (3h 5/6) and formyl (3i) groups.
Density function theory calculations showed that when bromine atoms introduced to 2, 6 position of aza-boron-dipyrromethene core, singlet and triplet energy levels get closer therefore probability of intersystem crossing increases.
When the bromine atoms are introduced to the 6,6′-positions of the BINOL unit as in ligand (S)- 2e, it should reduce the Lewis basicity of the central two oxygen atoms.
Besides causing beautiful opalescent colours, nacreous clouds' tiny ice crystals also act to encourage chemical reactions between ozone and the chlorine and bromine that we have introduced into the atmosphere by our use of substances such as chlorofluorocarbons (CFCs) in aerosols and fridge mechanisms.
A bulky modification such as bromine or trifluoromethyl was introduced at position 7 based on previous studies of the analogue 7BIO (7-bromoindirubin-3′ oxime; Table 1) that showed a minor negative influence on affinity due to a putative steric clash between the inhibitor and the kinase hinge.
An earlier shipboard study found that ozone introduced into salt water ballast resulted in the formation of bromine compounds, measured as total residual oxidants (TRO) that were toxic to both bacteria and plankton.
The blocks based on butyl acrylate and N-acryloyl morpholine form the core and shell of the micelles, respectively, while an additional d-mannosylated block, which forms the corona, is introduced applying a previously reported post-polymerisation functionalization of a reactive bromine precursor with α-d-thiomannose.
In an approach to increase the overall TMS substitution level as well as introduce these groups on the bisphenol segment, both TMPSf and TMPPSf were cleanly brominated to a degree of substitution (DS) of 2.0 for bromine.
