(8)]. The reaction of M(NR2)4 (M = Zr, Hf, R = Me, Et) with 1 and 2 failed. However, the zirconium and hafnium disubstituted complexes, [M(NR2)2κ2-N,E-(4,5-(P(E)Ph2)2tz}2] [M = Zr, E = S, R = Me (11), Et (12); M = Hf, E = S, R = Me (13), Et (14); M = Zr, E = Se, R = Et (15); M = Hf, E = Se, R = Et (16)] were obtained from the silylated derivatives [SiMe3κ1-N-(4,5-(P(E)Ph2)2tz}] [E = S(9), Se(10)] and
摘要配体[H 4,5-(P(E)Ph2)2tz}]的等摩尔和过量比率反应[tz = 1,2,3-三唑; E = S(1),Se(2)]与Ti(NR2)4(R = Me,Et)生成双取代的配合物[Ti(NR2)2 κ2-N,E-(4,5-(P( E)Ph2)2tz} 2] [E = S,R = Me(3),Et(4); E = Se,R = Me(5),Et(6)],而1和2的反应与Ti(NEt2)2Cl2得到单取代的配合物[Ti(NEt2)Cl2 κ2-N,E-(4,5-(P(E)Ph2)2tz}] [E = S(7),Se(8)] 。M(NR2)4(M = Zr,Hf,R = Me,Et)与1和2的反应失败,但是锆和ha双取代的配合物[M(NR2)2 κ2-N,E- (4,5-(P(E)Ph2)2tz} 2] [M = Zr,E = S,R = Me(11),Et(12); M =
