    Description / Table of Contents: Synthesis of Methyl(trimethylsilylamino) fluoroalkylphosphites and Methylamino-bis(fluoroalkylphosphites)Fluorochlorophosphites, ROPFCl I, react with heptamethyldisilazane with replacement of a trimethylsilyl group to give methyl(trimethylsilylamino)fluoroalkylphosphites, CH3N-(PFOR)(SiMe3) II. The introduction of a second PFOR substituent in II by further reaction with I has been possible. Thus formation of the previously unknown methylamino-bis(fluoroalkylphosphites), CH3N(PFOR)2 III, was observed. Compounds of type III exist in a meso form as well as in a racemic pair. 19F and 31P n.m.r. spectra are discussed.
    Notes: Fluorochlorophosphite, (ROPFCl) I, reagieren mit Heptamethyldisilazan unter Substitution einer Trimethylsilylgruppe zu Methyl-(trimethylsilylamino)-fluoroalkylphosphiten, CH3N(PFOR)(SiMe3) II. Unter drastischeren Bedingungen kann mit I auch die zweite Trimethylsilylgruppe substituiert werden und man erhält die bisher unbekannten Methylamino-bis(fluoroalkylphosphite), CH3N(PFOR)2 III. Letztere liegen in einer meso-Form bzw. als Racemat vor. Die 19F- und 31P-NMR-Spektren werden diskutiert.
