Name: 4-(Piperazin-1-yl)phenol. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about SuFEx-enabled, chemoselective synthesis of triflates, triflamides and triflimidates.

The ex-situ generation of trifluoromethanesulfonyl fluoride (CF3SO2F) gas in a two chamber system, and its use as a new SuFEx handle to efficiently synthesize triflates and triflamides were reported. This broadly tolerated protocol lends itself to peptide modification or to telescoping into coupling reactions. Moreover, redesigning the SVI-F connector with a S=O → S=NR replacement furnished the analogous triflimidoyl fluorides as SuFEx electrophiles, which were engaged in the synthesis of rarely reported triflimidate esters. Notably, experiments showed H2O to be the key towards achieving chemoselective trifluoromethanesulfonation of phenols vs. amine groups, a phenomenon best explained-using ab initio metadynamics simulations-by a hydrogen bonded termol. transition state for the CF3SO2F triflylation of amines.
Although many compounds look similar to this compound(56621-48-8)Name: 4-(Piperazin-1-yl)phenol, numerous studies have shown that this compound(SMILES:OC1=CC=C(N2CCNCC2)C=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
