以环十二酮为原料, 分别与溴代环己烷或苯基锂试剂反应制得2-环己基环十二酮和2-苯基环十二酮, 还意外获得了副产物1,1'-二羟基-1,1'-联环十二烷. 2-环己基环十二酮和2-苯基环十二酮与盐酸羟胺反应制备了2-环己基环十二酮肟和2-苯基环十二酮肟, 与亚硝酸钠-盐酸体系反应获得了3-环己基-1,2-环十二二酮单肟和3-苯基-1,2-环十二二酮单肟. 在溶液中结晶获得其中四个化合物单晶并进行了X射线衍射, 结果表明1-苯基环十二醇和1,1'-二羟基-1,1'-联环十二烷在晶体中的十二元环均采取[3333]构象, 两个取代基在角碳上; 在晶体中2-环己基环十二酮肟的十二元环采取[3333]-2-酮构象, 而3-苯基-1,2-环十二二酮单肟的十二元环则改变为[4233]-3,4-二酮构象, 取代基均在边碳外向位, 量子力学计算的结果与晶体衍射的结果一致. 1,1'-二羟基-1,1'-联环十二烷在晶体中采取摞光盘一样完全重叠的自组装排列方式.

2-Cyclohexylcyclododecanone and 2-phenylcyclododecanone were synthesized via reaction of cyclododecanone with bromocyclohexane and lithium phenide using cyclododecanone as raw material, respectivey. The 1,1'-dihydroxy-1,1'- bicyclododecane was also obtained unexpected. 2-Cyclohexylcyclododecanone oxime and 2-phenylcyclododecanone oxime were prepared by reaction of 2-cyclohexylcyclododecanone and 2-phenylcyclododecanone with hydroxylamine chloride, 3-cyclohexylcyclododecan-1,2-dione monooxime and 3-phenyl-cyclododecan-1,2-dione monooxime were synthesized by reaction of 2-cyclohexylcyclododecanone and 2-phenylcyclododecanone with NaNO2-HCl system. Their crystals were obtained in the solution and X-ray diffraction analyses were carried out. The results showed that [3333] conformation was took by the cyclododecane ring of 1-phenylcyclododecanol and 1,1'-dihydroxy-1,1'-bicyclododecane, the two substituted groups were at corner position, while 2-cyclohexylcyclododecanone oxime took [3333]-2-one, 3-phenylcyclododecan-1,2-dione monooxime took [4233]-3,4-dione conformation and the substituted groups were at side-exo position in their crystals. The results of quantum mechanics calculation were consistent with those of X-ray diffraction. In the crystal structure of 1,1'-dihydroxy- 1,1'-bicyclododecane, the molecules exhibited unique self-assembly property of complete disc overlapping between two molecular layers in the a-axis direction with intermolecular hydrogen bond.

Key words: cyclododecanone oxime, cyclododecan-1,2-dione monooxime, [3333] conformation, [3333]-2-one, [4233]-3,4- dione
