Abstract: | Reactions of rhodium(I) and iridium(I) chlorocomplexes of cyclohexa-1,3-diene, cyclohepta-1,3-diene, and cylo-octa-1,3,5-triene with AgBF4/CH2Cl2 afford respectively the cations M(C6H6)(1,3-C6H8)]+, M(η5-C7H7)(η5C7H9)]+ and M(η6-C8H10)(η4-C8H10)]+; the latter complex is a hydrogenation catalyst for olefins. |
