Abstract
1. Reaction of [Ph(CH2)n]2Hg (n=3, 4) with (NH3)3Cr(CO)3 or Cr(CO)6 affords the corresponding mono- and binuclear arenechromium tricarbonyl derivatives. 2. Treatment of the complexes [Ph(CH2)n]2Hg · [Cr(CO)3]2 with mercuric chloride gives the Ω-chloromercuri-substituted arenechromium tricarbonyls (CO)3Cr·Ph(CH2)n]2HgCl (n=3, 4), in which the mercury atom is not coordinated with the Cr(CO)6 groups. 3. The formation ofΩ-lithioalkylbenzenechromium tricarbonyls from theΩ-bromo compounds (CO)3Cr Ph(CH2)n]2Br (n=2,4) by standard methods proceeds with difficulty, and is accompanied by a number of byproducts.
