Pj. Dyson et al., THE SYNTHESIS, MOLECULAR AND CRYSTAL-STRUCTURE OF THE BIS(ARENE) HEXARUTHENIUM CARBIDO-CARBONYL ISOMERS RU6C(CO)(11)(C(6)H(4)ME(2)-1,3)(C(6)H(5)ME), Inorganica Chimica Acta, 235(1-2), 1995, pp. 413-420
The reaction of Ru6C(CO)(14)(eta(6)-C(6)H(4)Me(2)-1,3) (1) with dihydr
otoluene (C(6)H(7)Me) and Me(3)NO in dichloromethane yields O)(12)(eta
(6)-C(6)H(4)Me(2)-1,3)(mu(2)-C(6)H(7)Me) (2), Co)(11)(eta(6)-C(6)H(4)M
e(2)-1,3)(mu(3)-C(6)H(5)Me (3) and )(11)(eta(6)-C(6)H(4)Me(2)-1,3)(eta
(6)-C(6)H(5)Me) (4). Reaction of 1 with toluene and Me(3)NO in dichlor
omethane-acetone affords )(11)(eta(6)-C(6)H(4)Me(2)-1,3)(eta(6)-C(6)H(
5)Me) (5). On standing at room temperature 3 isomerises spontaneously
to 4. The molecular structures of 4 and 5 have been established by X-r
ay crystallography.
