Fluordiazadiphosphetidine, 10. Mitt.: Die Reaktion von 1,3-Dialkyl-2,2,2,4,4,4-hexaflouro-1,3,2λ5,4λ5-diazadiphosphetidine mitN-Trimethylsilylmethylamin

摘要

Reaction of (RNPF3)2compounds (R=CH3, C2H5,n-C3H7,n-C4H9,i-C4H9) withN-trimethylsilyl-methylamine leads to nucleophilic substitution of one or two fluorine atoms by the methylamino group, depending on the molar amounts of the reactants. In the case ofR=CH3, two by-products are formed: in the first step a compound with coordination numbers IV, V and VI for the three phosphorus atoms in C5H17F7N5P3and in the second step a monospiroflourodiaza-λ5, λ5-diphosphetidin
