合成了苯甲脒基钇二烷基配合物[PhC（NAr）（2）]Y（CH_2SiMe_3）（2）（THF）（n）（Ar = 2，6-二异丙基苯基; n = 1，2），当与[PhNMe_2 H][B（C_6 F_5）（4）]活化时，n = 1的配合物可使乙烯聚合成窄多分散性的聚乙烯。
The benzamidinate yttrium dialkyl complexes [PhC(NAr)(2)]Y(CH2SiMe3)(2)(THF)(n) (Ar = 2,6-diisopropylphenyl; n = 1, 2) were prepared; when activated with [PhNMe2H][B(C6F5)(4)] the species with n = 1 polymerises ethene to polyethene with a narrow polydispersity.
