Potassium-zinc induced synergic enhancement of the basicity of hexamethyldisilazide (HMDS) towards methylbenzene molecules

While neither KHMDS nor Zn(HMDS)2 can unilaterally metallate toluene under the conditions studied, the bilateral base 'KZn(HMDS)3' can smoothly do so to produce the benzyl product [[KZn(HMDS)2(CH2Ph)]infinity], which exists in the crystal as an infinite spiral chain of benzyl (ambi-sigma,...

Zusammenfassung:While neither KHMDS nor Zn(HMDS)2 can unilaterally metallate toluene under the conditions studied, the bilateral base 'KZn(HMDS)3' can smoothly do so to produce the benzyl product [[KZn(HMDS)2(CH2Ph)]infinity], which exists in the crystal as an infinite spiral chain of benzyl (ambi-sigma, pi)-linked (KNZnN) rings.
