    Description / Table of Contents: On the Different Mode of Addition of Ketones and Sulfoxides to Persilylated Aminodiimino-phosphoraneThe persilylated aminodi(imino)phosphorane [(CH3)3Si]2NP[=N—Si(CH3)3]2 (1) adds acetone and acetophenone to give the O-phosphorylated enoles 2. Thermolysis of 2 yields the diazadiphosphetidine 3 and the corresponding silylenol ethers 4. However, in the reaction of 1 with dimethyl sulfoxide or methyl phenyl sulfoxide the sulfur atom is reduced to a thioether structure with formation of the addition products 5.
    Notes: Das vollständig silylierte Aminodiiminophosphoran 1 [(CH3)3Si]2NP[=NSi(CH3)3]2 (1) reagiert mit Aceton und Acetophenon unter Addition zu den O-phosphorylierten Enolen 2. Ihre Thermolyse ergibt das Diazadiphosphetidin 3 sowie die entsprechenden Silylenolether 4. Mit Dimethylsulfoxid bzw. Methylphenylsulfoxid setzt sich 1 hingegen unter Reduktion des Schwefelatoms zu den Additionsverbindungen 5 um.
