Abstract
1,2,3,4,5,6-hexaalky1-1,4-dibora-2-cyclohexene은 B2Cl4로부터 제조할 수 있었으나, 보통실험실에서는 이것을 제조하기 어렵기 때문에 다른 방법에 의한 생성을 시도하였다. 즉 1,4-dimethyl-2,3-diethy1-1,4-dibora-2-cyclohexene,1 유도체를 potassium과 methyl iodide에 의한 환원 산화반응을 시켜주므로 2,3-diethyl-1,4,5,6-tetramethy1-1,4-dibeora-2-cyc1ohexene, 2를 얻을 수 있었다. 또 이 유도체와⒩·C5H5)Co(C2H4)2를 반응시켜 코발트 sandwich 착물인 두 종류의 double-decker, 6 그리고 7, 또 한 종류의 triple-decker, 8을 생성하였다.

1,2,3,4,5,6-Hexaalkyl-1,4-dibora-2-cyclohexene was not produced by the general preparation method in our laboratory because of difficulties in the preparation of B2Cl4. 2,3-Dietyl-1,4,5,6-tetramethyl-1,4-dibora-2-cyclohexene, 2 was synthesized by the reduction-oxidation reaction of potassium and methyliodide from 1,4-dimethyl-2,3-diethyl-1,4-dibora-2-cyclohexene, 1 as a substrate. Cobalt sandwich-complexes, 6, 7 and 8 were synthesized by the reaction of 2,3-diethyl-1,4,5,6-tetramethyl-1,4-dibora-2-cyclohexene with (η5-C5H5)Co(C2H4)2.
