Molecular devices are reported utilizing active self-assembled monolayers containing the nitroamine @28-amino-4,48-di~ethynylphenyl!-58-nitro-1-benzenethiolate# or the nitro compound @4,48-di~ethynylphenyl!-28-nitro-1-benzenethiolate# as the active components. Both of these compounds have active redox centers. Current–voltage measurements of the devices exhibited negative differential resistanc...

The reactions employ small organic molecules as catalyst under mild reaction conditions and do not ...

Magnetically separable gold-nanoparticle catalyst was prepared, and it showed excellent activity for chemoselective reduction of nitroarenes with hydrosilanes.

Abstract A method for the synthesis of functionalized piperidines containing 3 contiguous stereocentres in 2-,3- and 4- positions uses a diastereoselective nitro-Mannich to control stereochemistry. The reaction between β-aryl/heteroaryl substituted nitroalkanes glyoxylate imine provides β-nitro-amines with good selectivity (70:30 >95:5) syn, anti-diastereoisomers. Reductive cyclisation BF3.OEt2...
