Covalent functionalization of carbon nanotube forests grown in situ on a metal-silicon chip [PDF]

, 2012
We report on the successful covalent functionalization of carbon nanotube (CNT) forests, in situ grown on a silicon chip with thin metal contact film as the buffer layer between the CNT forests and the substrate.

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, Volume 4, Issue 2, February 2026.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

Thermolysis of imidates: A new method for the generation of carbonyl ylides [PDF]

, 2007
Thermolysis of dimethyl 2-[(3-oxo-3H-isoindol-1-yl)oxy]malonate (8) promotes a [1,4]-H shift in the imidic N¼C O CH fragment of the starting molecule, which leads to a reactive carbonyl ylide.
