  Remarkable Effect of Valence Electrons in Thiolato-Bridged Diruthenium Complexes toward Catalytic Dimerization of α-Methylstyrenes

  摘要：

  The dicationic diruthenium complex 1c (Ru-III-Ru-III) catalytically promotes the dimerization of alpha-methylstyrenes into the corresponding acyclic dimers, while the use of the mixed-valence diruthenium complex (Ru-III-Ru-IV) 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 alpha-methylstyrenes depends on the nature of electrophilicity due to valence electrons in the diruthenium cores between Ru-III-Ru-III and Ru-III-Ru-IV.
