IONIC IRIDIUM-GOLD AND RHODIUM-GOLD PERFLUOROBENZENETHIOLATO BINUCLEAR COMPLEXES - SYNTHESES AND SOLUTION BEHAVIOR

摘要

By reacting [(C(5)Me(5))M(SR(F))(2)] (for M=Ir, R(F)=C6F5 (1a) or C6F4H-p (1b); for M=Rh, R(F)=C6F5 (2a) or C6F4H-p (2b)) in toluene with Na[AuCl4], ionic binuclear compounds with the general formula [(C(5)Me(5))M(mu-SR(F))(2)AuCl2]Cl (for M=Ir, R(F)=C6F5 (3a) or C6F4H-p (3b)); for M=Rh, R(F)=C6F5 (4a) or C6F4H-p (4b) can be obtained, together with small amounts of [(C(5)Me(5))(2)Rh-2(mu-SR(F))(mu-Cl)(2)]Cl (R(F)=C6F5 (5a) or C6F4H-p (5b)) as by-products when 2a and 2b were used.
