In the presence of organolithium bases phenyl dialkylcarbamates have previously been shown to undergo facile rearrangement to yield the corresponding salicylamides. However, heterometallic lithium diethyl(2,2,6,6- tetramethylpiperidido)zincate achieves the clean directed ortho-metallation (DoM) of phenyl dialkylcarbamates, with [C6H4{OC(O)- NMe2}{Zn(μ-TMP)Et}Li]2 having been structurally characterized. DFT studies point to a stepwise deprotonative mechanism in which the zincate reagent exhibits kinetic amido basicity.
