六核簇状化合物的系统合成路线
A systematic synthetic route to the hexanuclear cluster compound [Ru 6 C(CO) 13 (η 5 -C 5 H 3 Ph 2 )(µ 3 -CPh)] has been elaborated in which a number of stable intermediates have been isolated and characterised. The reaction of [Ru 6 C(CO) 17 ] with Me 3 NO and phenylacetylene afforded the alkyne derivative [Ru 6 C(CO) 15 (PhC 2 H)] 1. Further treatment of 1 with Me 3 NO and an excess of phenylacetylene resulted in the formation of two isomers [Ru 6 C(CO) 14 {C(Ph)CHC(Ph)CH}] 2 and [Ru 6 C(CO) 14 {C(Ph)CHCHC(Ph)}] 3. Both contain five-membered metallocyclic rings formed by the head-to-head coupling of phenylacetylene in one isomer and the head-to-tail coupling in the other. Reaction of isomer 2 with Me 3 NO and phenylacetylene leads to [Ru 6 C(CO) 13 (η 5 -C 5 H 3 Ph 2 )(µ 3 -CPh)] 4. The molecular structure of one of the isomers, 3, has been established by single-crystal X-ray crystallography.
