U. Azzena et al., REDUCTIVE ELECTROPHILIC SUBSTITUTION OF DIARYLMETHYL METHYL ETHERS - SYNTHETIC APPLICATIONS, Synthetic communications, 24(5), 1994, pp. 591-599
The reductive cleavage of diarylmethyl methyl ethers with Li metal in
THF led to quantitative formation of the corresponding diarylmethyl an
ions. Quenching with electrophiles afforded substituted diarylmethanes
in good to excellent yields.
