Silafunctional compounds in organic synthesis. 46. Platinum-catalyzed intramolecular hydrosilation of allylamines: formation of 1-aza-2-silacyclobutanes and application to stereoselective synthesis of 2-amino alcohols
A non-enzymatic acetyl transfer-based kinetic resolution of primary allylic amines is reported. The process involves the use of (1S,2S)-1 in conjunction with a supported ammonium salt and affords the corresponding enantio-enriched N-acetylated allylic amines with unprecedented levels of selectivity (s-factors up to 34).

Disclosed are methods of using nitrogen-containing compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using 2-substituted imidazoles and 2-substituted benzimidazoles, and provides enhanced protection against corrosion of metals in the aqueous system. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising 2-substituted imidazoles and 2-substituted benzimidazoles are also disclosed.
