Naphthoxide ion
Witryna1 kwi 1992 · Attack of the naphthoxide ion nucleophile at the epoxide ring is also possible, as is cleavage of the ring by water. Therefore the products shown in Scheme 2 were expected. From parallel reactions The a-naphthoxide ion is an ambidentate anion, capable of covalency formation at the oxygen or the a-carbon, giving 1-(1-naphthoxy) … Witrynacooled ion trap operated at 4.6 K. After being accumulated for 0.1 s and cooled via collision with a He/H 2 (4/1 volume ratio) buffer gas,41 the cold anions were pulsed out at a 10 Hz repetition rate into a time-of-flight mass spectrometer. The desired 2-naphthoxide anion was selected by using a mass gate and photodetached in
