The reaction of Ru₃(CO)₁₂ with five-membered cyclic SP(S)(Fc)N(Ph)NC(Me) gave two novel trinuclear and tetranuclear ruthenium carbonyl clusters containing capping S atoms in Ru₃(CO)₈(μ₃-S)₂[P(Fc)N(Ph)NC(Me)S] 1 and Ru₄(CO)₇(μ-CO)₃(μ₄-S)₂[P(Fc)N(Ph)NC(Me)S] 2 (Fc=C₅H₅FeC₅H₄). During the reaction, the ligand precursor cleaved only in its P=S bond to give the fragments S and [P(Fc)N(Ph)NC(Me)S], and then coordinated to the ruthenium atoms to form the clusters as listed above. The clusters have been characterized by elementary analysis, IR, ¹H NMR and MS spectroscopy. The crystal structure of cluster 2 has been determined by X-ary diffraction techniques. The crystal belongs to monoclinic with space group P2₁/c. The unit cell parameters are as follows: a=1.18744(7) nm, b=1.36041(11) nm, c=2.20026(18) nm, β=104.126(3) °, V=3.4468(5) nm³, D_c=2.175 g·cm^-3, Z=4. In the molecule, the three bridging carbonyls and Ru4 are planar and with a pseudo-octahedral Ru₄S₂ skeleton. The terminal carbonyl of Ru1 was substituted by the cyclic ligand [P(Fc)N(Ph)NC(Me)S].

含有烯丙基亚胺酚配体的ⅣB族烯烃聚合催化剂以及制备双峰分布聚乙烯(英)

选择含有烯丙基亚胺酚为辅助配体，设计合成了5个ⅣB族钛锆金属络合物[{CH₂=CHCH₂N=CH-C₆H₃(3-R)O}₂MCl₂](4a：R=t-Bu，M=Zr；4b：R=t-Bu，M=Ti；4c：R=Ph，M=Zr；4d：R=Ph，M=Ti)和[{(CH₃)₂CHCH₂N=CH-C₆H₃(3-t-Bu)O}₂ZrCl₂] (5)，对它们进行了红外光谱、核磁共振及元素分析表征。并用X-射线单晶衍射法测定了化合物4a和4d的晶体结构。部分配合物在助催化剂MMAO的作用下对烯烃聚合显示了较好的催化活性，其中自固载催化剂4a生成了双峰分布的聚烯烃产品 (M_w/M_n=15.3～31.9)。
