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.
