using a phosphetane oxide catalyst in the presence of a simple organosilane as the terminal reductant and water as the hydrogen source. Quantitative hydrogenation was observed when 1.0 mol % of a methyl‐substituted phosphetane oxide was employed as the catalyst. The procedure is highly selective towards activated double bonds, tolerating a variety of functional groups that are usually prone to reduction

A rhodium(III)-catalyzed direct cross-coupling reaction of indolines with maleimides via C–H bond activation was developed. This protocol displays good functional group tolerance, which offers a novel approach to access C7 modified indoline derivatives including maleimide analogues.
The present invention is in the field of flame retardants and relates to use of sulfenamides as flame retardants, in particular in polymeric substrates.
