Aminoisoquinolines as colorimetric Hg2+ sensors: the importance of molecular structure and sacrificial base
摘要:
Here it is shown that 3-phenyl-2-amino isoquinoline acts as a simple mercury sensor. It is simple to synthesize. The molecule requires base/buffer to bind in a 1:1 stoichiometry with mercury ion. however. Otherwise, it acts as a sacrificial base, presumably to pick up a proton liberated during binding. This binding is characterized quantitatively. (C) 2009 Elsevier Ltd. All rights reserved.

A novel and regioselective Ni(I) catalyzed C–C and C–N cascade couplingreactions has been developed. The cascade furnishes atom-economic access to 40 3-aryl-1-aminoisoquinolines. The regioselectivity of C(sp3)-cyano group over C(sp2)-cyano group was revealed and supported by mechanism studies as well as the preliminary density functional theory (DFT) calculations.
Two molar amounts of arynes were found to couple with nitriles via carbonâcarbon Ï-bond cleavage, assembling diverse diarylmethane skeletons in a straightforward manner.
