Abstract

Toluene is metallated by DABCO-activated disodium tetrabutylmagnesiate, but not by DABCO-activated monosodium tributylmagnesiate; this distinction is rationalised by DFT calculations on model systems, and the crystal structure of the main non-metallated product, which shows interstitial MgBu42- dianions within a polycationic network, is reported.
