The dicationic diruthenium complex 1c (RuIII-RuIII) catalytically promotes the dimerization of α-methylstyrenes into the corresponding acyclic dimers, while the use of the mixed-valence diruthenium complex (RuIII-RuIV) generated from 1c and cinnamyl chloride as an active catalyst affords the corresponding indanes via cyclization of the acyclic dimers. The selectivity of the catalytic dimerization of α-methylstyrenes depends on the nature of electrophilicity due to valence electrons in the diruthenium cores between RuIII-RuIII and RuIII-RuIV.
