Strong Evidence for a Transient Phosphinidenoid Complex

Caught in the trap: Two different routes to the thermally unstable phosphinidenoid complex I are described, and chemical evidence for this novel intermediate is provided through selective reactions. For example, methyl iodide, dimethylcyanamide, or butyraldehyde furnished complexes II, III, and IV (...

Description
Summary:Caught in the trap: Two different routes to the thermally unstable phosphinidenoid complex I are described, and chemical evidence for this novel intermediate is provided through selective reactions. For example, methyl iodide, dimethylcyanamide, or butyraldehyde furnished complexes II, III, and IV (see scheme) under very mild conditions.
