 Title    Synthesen und Eigenschaften von Piperidin-N-oxyboranen Synthesis and Properties of Piperidine-N-oxyboranes  
 Abstract    Piperidine-N-oxyboranes and 2,2,6,6-Tetram ethylpiperidine-N -oxyboranes have been p re­ pared starting from halogenoboranes by three methods: a) By reaction with N-hydroxypiperidine and triethylam ine; b) by cleavage of the Si —O-bond in piperidine-N-oxy-trim ethylsilanes and c) by reaction with metallated piperidine-N-oxy compounds. Diboryloxides and diborylamides, resp., are obtained upon reaction of piperidine-N-oxy-brom oboranes with hexamethyldisiloxane and hexamethyldisilazane. Steric influences upon reac­ tivity and spectroscopic properties are discussed. The com pounds are characterized by elem ental analysis, mass and NMR spectroscopy ('H , "B , 13C , 14N , 29Si). A n X-ray analysis has been carried out for tris(2,2,6,6-tetram ethylpiperidine-l-oxy)borane 13.
