Abstract |
트리플 데카 착물, bis(η5-cyclopentadienyl)-μ-(η6-2,3-dialkyl-1,4-dimethyl-1,4-dibora-2,5-cyclohexadiene)dicobalt 1을 합성하고, 이것을 출발물질로 하여 여기에 3-hexyne을 과량으로 반응시켰더니 두 종류의 sandwich 착물인 cyclopentadienyl(η6-2,3-dialkyl-1,4-dimethyl-1,4-dibora-2,5-cyclohexadiene)cobalt 2와 cyclopentadienyl(η6-hexaethyl benzene)cobalt 3의 고리화 반응 생성물인 hexaethyl benzene이 생성되었음을 확인하였다. A tripledecker sandwichcomplex, bis(η5-cyclopentadienyl)-μ-(η6-2,3-dialkyl-1,4-dimethyl-1,4-dibora-2,5-cyclohexadiene)dicobalt 1 was synthesized as a starting material. By the reaction of compound 1 with the excess 3-hexyne two kinds of sandwichcomplexes, cyclopentadienyl(η6-2,3-dialkyl-1,4-dimethyl-1,4-dibora-2,5-cyclohexadiene)cobalt 2 and cyclopentadienyl(η6-hexaethyl benzene)cobalt 3 were separated. The complex 3 was decomposed during purifying at RT to give a cyclization product of 3-hexyne, hexaethyl benzene. |
