ORGANOMETALLIC CHEMISTRY - THE STRUCTURE OF ARYLMERCURY DERIVATIVES OF ALIZARIN AND THEIR INTERACTION WITH ANIONS

The structure of mono- and di-ArHg-derivatives of alizarin (1,2-dihydr oxy-9,10-anthraquinone) and their interactions with halide- and oxygen -containing salts are examined by vibrational and electronic spectrosc opy. The interaction of solid mono- and di-ArHg-derivatives of alizari n with bromides results only in the formation of the monoanion or the ion pair, depending on the nature of the counterion. Dianions are form ed in a DMSO solution with very great excess of the bromide.
