Paragraph 0044-0047, (2019/10/08)
The invention discloses a colorimetric probe capable of continuously detecting hydrogen sulfate and mercury ions and a synthesis method and application thereof. The colorimetric probe is prepared by successive reactions of 2-halogenated pyridine, 5-aldehyde-2-thiopheneboronic acid, [Ru(cycme)Cl2]2, 2,2'-bipyridyl and 3-ethyl-2,3-dihydro-1,1,2-trimethyl-1H-benzo[e]indolehexafluorophosphate. The colorimetric probe can respectively or continuously detect HSO3 and Hg in a water solution, and especially has a more obvious in-situ detection effect on Hg after an action with HSO3. The colorimetric probe of the invention has high sensitivity and good selectivity.

A total of 19 alkylated heterocycles (thiophenes, benzothiophenes, pyrroles, furans) were prepared (36-99% yield) from the respective pyridin-2-yl-substituted precursors employing alkylboronic acids as the C-H alkylating reagents in an oxidative (Ag2
