Platinum(II) complexes with amide-functionalized NHC ligands
摘要:
We present the synthesis of neutral, amide-functionalized N-heterocyclic carbene (NHC) platinum(II) complexes with dianionic -N-C-NHC-C-NHC-N- (NC*C*N) tetradentate ligands. The imidazolium- and bisimidazolium bromide NHC ligand precursors with amide functionality in the side chain are reported together with the corresponding biscarbene bromido complexes and, after deprotonation, of the neutral NHC complexes without counterions. All compounds have been thoroughly characterized by standard techniques. (C) 2012 Elsevier B. V. All rights reserved.

Omega-((hetero)alkyl)benz(cd)indol-2-amines useful in inhibition of thromboxane synthetase and in treatment of hypertension in warm-blooded animals are disclosed.
Omega-[(hetero)alkyl]benz[cd]indol-2-amines useful in inhibition of thromboxane synthetase and in treatment of hypertension in warm-blooded animals are disclosed.
In this study, 15 omega-(1H-imidazol-1-yl)-N-phenylacetamide, propionamide and butyramide derivatives having methoxyl, methyl, nitro and chloro in ortho position of N-phenyl ring or without any substituent have been realized by two-step synthesis. Their anticonvulsant activity was determined against seizures induced by maximal electroshock (MES). The most active compound in the series was 2-(1H-imidazol-1-yl)-N-(o-chlorophenyl)acetamide.
