An expedient preparation of 9-fluoronylmethanol

Chong,Lajoie,Tjepkema

, p. 819 - 820 (1992)

Lithiation of fluorene in tetrahydrofuran with butyllithium followed by reaction with paraformaldehyde provides a convenient one-pot preparation (~70% isolated yield) of 9-fluorenylmethanol. The yield of 9-fluorenylmethanol is critically dependent on stoichiometry and reaction times.
