Method for the synthesis of cationic arene complexes of group VII and group VIII metals in strong Broensted acids
A review of the work on the synthesis of the title complexes has been presented. The interaction of (Ru(eta-C/sub 6/H/sub 6/)Cl/sub 2/)/sub 2/ (I) with AgBF/sub 4/ or AgNO/sub 3/ in an aqueous medium gives (Ru(eta-C/sub 6/H/sub 6/)(H/sub 2/O)/sub 3/)/sup 2 +/, which reacts with arenes in CF/sub 3/COOH to form (Ru(eta-C/sub 6/H/sub 6/)(n-arene))/sup 2 +/ (II). The same complexes have been obtained from complex I by reacting it with arenes in heptane in the presence of AlCl/sub 3/. It has been found that cations II form when complex I is boiled directly with arenes in CF/sub 3/COOH, and in the cases of C/sub 6/H/sub 6/, C/sub 6/Me/sub 6/, and naphthalene, they form at room temperature in H/sub 2/SO/sub 4/. The complexes (Os(eta-Me/sub 3/C/sub 6/H/sub 3/)(n-arene))/sup 2 +/ have been obtained by boiling (Os(eta-Me/sub 3/C/sub 6/H/sub 3/)Cl/sub 2/)/sub 2/ with the arene in CF/sub 3/COOH. The complexes (M(eta-C/sub 4/Me/sub 5/)-(eta-arene))/sup 2 +/ (M = Rh, Ir) have been obtained in a similar manner from (M(eta-C/sub 5/Me/sub 5/)Cl/sub 2/)/sub 2/. Hypotheses regarding the structure of the intermediates formed during the reactions investigated have been advanced.
