Experimental kinetics confirm that these twisted cyclodecynes can be more reactive toward azides than activated cyclononynes and approach the reactivity of cyclooctynes.
Phenols are highly reactive toward electrophilic aromatic substitution, because the nonbonding electrons on oxygen stabilize the intermediate cation.
Grignard reagents commonly are prepared by reaction of an organohalogen with magnesium in a nitrogen atmosphere because the reagent is very reactive toward oxygen and moisture.
Silanes are also very reactive toward hydroxides, producing silicate ions and hydrogen gas.SiH4 + 2OH− + H2O → SiO32− + 4H2In contrast, hydrocarbons are inert to hydroxides.
Titanium cannot be obtained by the common method of reducing the oxide with carbon because a very stable carbide is readily produced, and, moreover, the metal is quite reactive toward oxygen and nitrogen at elevated temperatures.
A cursory glimpse at tomorrow's rumored announcements shows a company that continues to be somewhat reactive toward industry moves.
First, model studies confirmed that aldehyde functions on the polymer chain remain reactive toward phenolic compounds.
Instead, we find that epitaxial graphene is rather reactive toward water molecules.
The isocyanate species was found to be highly reactive toward NO2.
The main fraction of sulfur in all springs was not reactive toward cyanide (>59% in all pools).
The side surfaces of nanorods are thus passivated by PVP, while the ends remain reactive toward silver atoms.
