Facile synthesis of mixed O, S or Se bearing hexasubstituted benzenes and their potential as Cu(ii) ion probe.

Summary of "Facile synthesis of mixed O, S or Se bearing hexasubstituted benzenes and their potential as Cu(ii) ion probe."

The present study offers a facile route for the synthesis of unsymmetrical hexasubstituted benzenes bearing alternate heteroatoms (O, S and Se) with the formula [1,3,5-(RSeCH2)3-2,4,6-(R'ECH2)3C6] (E = O, S or Se). The synthetic protocol involves the use of an in situ generated tris(selenonium) ion followed by treatment with another nucleophile affording the targeted species in >70% yields. The unsymmetrical hexasubstituted derivatives were characterized on the basis of physicochemical and spectroscopic data and in a representative case with single crystal X-ray study. The current work assumes great significance as the potential of these species as "turn-off" chemical sensors for Cu2+, which is a biologically and environmentally crucial metal ion, was also successfully demonstrated by 5a which bears alternate oxygen and selenium centres.

Medical and Biotech [MESH] Definitions

A subset of plants bearing a vascular system; examples are ferns and seed-bearing species.

A subset of various vascular plants (also known as the Tracheophyta) which include seed-bearing and non seed-bearing species.

The physical state of supporting an applied load. This often refers to the weight-bearing bones or joints that support the body's weight, especially those in the spine, hip, knee, and foot.

A group of compounds which can be described as benzo-pyrano-furano-benzenes which can be formed from ISOFLAVONES by internal coupling of the B ring to the 4-ketone position. Members include medicarpin, phaseolin, and pisatin which are found in FABACEAE.

A plant division. They are simple plants that lack vascular tissue and possess rudimentary rootlike organs (rhizoids). Like MOSSES, liverworts have alternation of generations between haploid gamete-bearing forms (gametophytes) and diploid spore-bearing forms (sporophytes).
