摘要：

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.
