Abstract |
트리플데카 착물류, bis-(η5-cyclopentadienyl)-μ-(η4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt들은 Jonas 시약과 2-hexyne 또는 3-Hexyne을 실온에서 동량으로 반응시킬 때, 50% 이상의 최대 수율이 얻어졌다. 한 종류의 트리플데카 착물인 bis-(η2-cyclopentadienyl)-μ-(η4-1,2,3,4-tetraethyl cyclobutadiene)dicobalt(13)는 실온에서 3-hexyne과 반응시키면, 착물 (η5-cyclopentadienyl)cobaltacyclopentadiene-μ-(η4-2,4-cobaltacyclopentadiene)(η5-cyclopentadienyl)cobalt(15)로 이성화되었다. 다른 한 종류의 트리플데카 착물, bis-(η5-cyclopentadienyl)-μ-(η4-1,3-dimethyl-2,4-dipropyl cyclobutadiene)dicobalt(14)를 2-hexyne과 반응시켰더니 1,3,5-trimethyl-2,4,6-tripropylbenzene 화합물이 생성되었다. The tripledecker complexes, bis-(η5-cyclopentadienyl)-μ-(η4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt were produced by the reaction of Jonas reagent with 2-hexyne and 3-hexyne in the maximum yield (above 50%) when they were reacted in eq-molar amounts at room temperature. A tripledecker complex, bis-(η2-cyclopentadienyl)-μ-(η4-1,2,3,4-tetraethyl cyclobutadiene)dicobalt(13) was isomerized to (η5-cyclopentadienyl)cobaltacyclopentadiene-μ-(η4-2,4-cobaltacyclopentadiene)(η5-cyclopentadienyl)cobalt(15) on reacting with 3-hexyne at room temperature. Another tripledecker complex, bis-(η5-cyclopentadienyl)-μ-(η4-1,3-dimethyl-2,4-dipropyl cyclobutadiene)dicobalt(14) was decomposed to give 1,3,5-trimethyl-2,4,6-tripropylbenzene through an intermediate complex by the reaction of 2-hexyne. |
