摘要有一双chelatingaminotropone的Ti建筑群的合成和结构[在上]ligand被报导了。功能的理论(DFT)学习的密度的计算建议当与methylaluminoxane(毛)激活时，二度(aminotropone)Ti建筑群为olefinic单体的聚合有高潜力。这些理论研究也证明活跃种类通常从二度(aminotropone)导出Ti催化剂与用二度(phenoxyimine)生产的那些相比拥有更高的electrophilicity自然作为高效石蜡聚合催化剂被知道的Ti建筑群(TiFI催化剂)。二度(aminotropone)Ti催化剂产生比TiFI有更高的electrophilicity的催化地活跃的种催化剂。
