General description

PVC membrane electrode based on bis(2-nitrophenyl)disulfide carrier acts as sensor for zinc ions. Bis(2-nitrophenyl) disulphide undergoes mechanochemical grinding with bis(4-chlorophenyl)disulfide in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene catalyst via metathesis reaction to yield non-symmetrical heterodimer 4-chlorophenyl-2′-nitrophenyl disulfide.

A PVC membrane electrode based on bis(2-nitrophenyl)disulfide carrier exhibits a very good response for Zn(2+) in a wide concentration range (from 2.9x10(-7) to 3.2x10(-2) mol l(-1)) with a slope of 29.9+/-0.4 mV per decade of Zn(2+) concentration. The response time

Mechanochemical reactions effected by milling or grinding are an attractive means to conduct chemical reactions dependent on molecular recognition and to systematically explore different modes of molecular self-assembly. The natural relationship between milling mechanochemistry and supramolecular chemistry arises primarily from

This work describes, for the first time, the application of combined pressure and temperature stimuli in disulfide metathesis reactions. In the system studied, above a pressure of 0.2 GPa, equimolar amounts of symmetric disulfides bis 4-chlorophenyl disulfide [(4-ClPhS)2 ] and bis
