On the other hand, 4'-chlorobenzanilide ((p-Cl-C(6)H(4))NHCPh([double bond]O)) reacts with R(3)Al to produce trimeric, twelve-membered ring aluminum compounds [R(2)Al[mu, eta(2)-(p-Cl-C(6)H(4))NC(Ph)O]](3) (14
将提出影响铝上的酰胺基基团的配位模式的因素。N-叔丁基烷基乙酰胺((t)BuNHCR([双键] O))与1.1摩尔当量的Me(3)Al在回流己烷中的反应得到五配位二聚化合物[Me(2)Al [eta(2) )-(t)BuNC(R)(mu(2)-O)]](2)(3,R = p-(t)Bu-C(6)H(4); 4,R = 2,6 -F,FC(6)H(3); 5,R = Me; 6,R = CF(3); 7,R = pF(3)CC(6)H(4))。但是,在2.2摩尔当量的Me(3)Al存在下,N-叔丁基-4-叔丁基苯甲酰胺((t)BuNHC(p-(t)Bu-C(6)H(4))(在回流己烷中的[双键] O得到[Me(2)Al [η(2)-(t)BuNC(p-(t)Bu-C(6)H(4))(mu(2)-O) ] AlMe(3)],8.与之相反,R'NHCR''([双键] O)与1摩尔当量的R(3)A
