ENHANCED NUCLEOPHILIC REACTIVITY OF A 4-LITHIOPHENOXIDE ION AND ITS APPLICATION TO THE SYNTHESIS OF A BIS(4-HYDROXYPHENYL)METHYLENECYCLOPENTADIENE AND ITS DIANION, A NOVEL EXTENDED TRIMETHYLENEMETHANE DIANION
H. Kurata et al., ENHANCED NUCLEOPHILIC REACTIVITY OF A 4-LITHIOPHENOXIDE ION AND ITS APPLICATION TO THE SYNTHESIS OF A BIS(4-HYDROXYPHENYL)METHYLENECYCLOPENTADIENE AND ITS DIANION, A NOVEL EXTENDED TRIMETHYLENEMETHANE DIANION, Chemistry Letters, (9), 1997, pp. 947-948
2,6-Di-tert-butyl-4-lithiophenoxide ion has enhanced nucleophilic reac
tivity probably due to intramolecular electronic repulsion and ifs rea
ction with 6,6-bis(dimethylamino)fulvene affords a novel extended trim
ethylenemethane dianion with a fulvene moiety whose NMR spectra indica
te substantially strong tetrapolar properties.
