n-butyl-lithium and lithium naphthalenide at temperatures ranging between −78 and −50°C leads to N-lithio-N-(2-lithioethyl)- and N-lithio-N-(3-lithio-propyl)benzamide [(8), (9)], which by treatment with different electrophiles (H2O, D2O, Me2S2, CO2, Pr1CHO, PhCHO, Me2CO, Ph2CO, and O2) yields the expected functionalized benzamides [(10), (11)]. The acidic and basic hydrolysis of compounds (10) and (11) gives different
