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) … WitrynaThe 1-naphthoxide ion has negative charge on the oxygen and the 2 and 4 carbons. This can be seen in resonance structures such as this: Since oxygen is significantly more electronegative than carbon we would expect the resonance structure with the negative charge on the oxygen to be the major contributor and so the charge density will be …
