Cyclic vs. acyclic alkyne towards Hg²⁺ ion detection: combined experimental and theoretical studies

Abstract

Alkynes constitute a versatile class of functional groups, which can potentially undergo a variety of transformations in organic synthesis. The interaction between alkyne unit and Hg2+ ion is well-known since...

Strategic design of a 2,6-disubstituted pyridine-based probe having hard-soft centers: responsive divergence from one core

“…Such interactions are feasible according to the HSAB principle, but literature reports are rather rare. [10][11][12] The Hg 2+ ion is known to have a high affinity towards the alkyne functionality, and therefore it is anticipated to serve as a potential interactive unit towards any kind of alkyne, but the nature of such interactions in different alkynes with similar surroundings of probes has not been explored yet. The Hg 2+ ion is also well-known to bind with hard donors like N and O atoms; [13][14][15][16][17] however, any insight about the nature of interaction of Hg 2+ in the presence of both hard and soft centres, simultaneously in a probe, is rather very rare.…”
