The rate of ortho-lithiation of anisole is accelerated dramatically in the presence of TMEDA, effective also in sub-stoichiometric amounts: Tetrahedron Lett., 35, 385 (1994). For discussion of the mechanism of ortho-lithiation, see: J. Org. Chem., 62, 3024 (1997). Although direct dilithiation with n-BuLi/TMEDA was unsuccessful, a sequence involving monolithiation, silylation and further lithiation at the 6-position gave the 2,6-disilyl derivative in 72% yield: J. Org. Chem., 49, 4657 (1984).
Widely used as a carbocation scavenger in the deblocking of, e.g. N-Boc or N-Cbz (Z) peptides with acidic reagents. Addition of anisole removes t-butyl or benzyl cations from the reaction mixture; see, e.g.: J. Chem. Soc., Chem. Commun., 922 (1976); Chem. Pharm. Bull., 25, 2929 (1977); Chem. Ber., 101, 3649 (1968).
