Abstract

Abstract 1 H-und neue 13 C-NMR-spektroskopische Untersuchungen liefern weitere Beweise dafür, daß 1 im Grundzustand als N, N-Bis (trimethylsilyl) formamid (1A), 2 dagegen als N, O-Bis-(trimethylsilyl) acetimidat (2B) vorliegt. Dennoch zeigt 2 gleiches chemisches Verhalten wie 1: Mit Benzoylaceton (5) reagiert 2 zum O-Silylenol 7 mit Cyanessigsäure-methylester (6) zum Olefin 8. N-tert-Butyl (trimethylsilyl) formamid 9 ...
