ChemInform Abstract: THERMAL REARRANGEMENT OF O‐ARYLSULFONYL‐N‐PHENYLHYDROXYLAMINES

Abstract

Bei. der Oxidation mit Bleidioxid erhält man aus dem N‐Benzolsulfonyl‐hydroxymamin (I) unter Umlagerung der Ester (II), während die entsprechende N‐Benzoylverbindung (III) zunächst zu (IV) oxidiert wird und sich bei 150°C in (V) umlagert.

Microfabrication of Helmholtz Coils with Integrated Channels for NMR Spectroscopy

“…Our technology is similar to that of Heuschkel et al, who laminated a Riston film onto the SU-8 channel structures [7]. Instead of Riston, we use a new method laminating a nonpolymerized SU-8 membrane, which can be structured by photolithography after lamination.…”

“…Polyimide has good chemical and thermal stability and is biocompatible [6]. SU-8 is another polymer, which has excellent mechanical properties, allows high aspect ratio structures and is biocompatible [7], [8], [9]. Chuang et al give an overview to different channel fabrication methods using SU-8 [10].…”
