Cyclooligomerization of 1-ethynylazulenes 1a,b, 6 and 7 as well as 1,2-bis(azulen-1-yl)ethynes 10a,b and 11 with CpCo(CO) 2 to the corresponding 1,2,4-tris(azulen-1-yl)benzenes 14a,b, 18 and 19 as well as [bis- and tetrakis(azulen-1-yl)cyclobutadiene]cobalt complexes 17a,b, 30a,b and 31 is described.
使用 CpCo(CO) 2 将 1-ethynylazulenes 1a,b, 6 和 7 以及 1,2-bis(azulen-1-yl)ethynes 10a,b 和 11 环低聚成相应的 1,2,4-tris(描述了 azulen-1-yl) 苯 14a、b、18 和 19 以及 [双和四 (azulen-1-基) 环丁二烯]钴配合物 17a、b、30a、b 和 31。
