In this paper we prepared a series of azacrown ethers with side chains of tropone rings and their derivatives by the reactivity of seven-membered aromatic tropone rings.
The paper deals with the fact that chemical modification and crosslinkage can increase the reactivity of cellulose fibers to dyes and the raise of fixation can thus be achieved.
Nitrene is a very important kind of of ganic active intermediate to synthesize the compounds containing nitrogen,which has the characters of high reactivity,diversity of reaction type and so on.
For example, there is a contribution that temperament makes to the acquisition of resilience; some people are simply born with less reactivity to stress.
The first is reactivity or negative emotionality, referring to general negative mood, intense negative reactions, and distress either when limits are imposed (eg, anger) or in new situations (eg, fear).
This is an example of cross reactivity, like if you're allergic to cashews you might also be allergic to pistachios or mangos since they're all in the same plant family.
