cyclopentadienyl derivative Sn[(CH2)4Sn(C5H5)Ph2]4 (5) as well as the transition metal substituted derivatives Sn[(CH2)4SnCo(CO)4}Ph2]4 (6), Sn[(CH2)4SnFe(CO)2C5H5}Ph2]4 (7), and Sn[(CH2)4SnMn(CO)5}Ph2]4 (8) have been prepared by coupling of 3 with the appropriate Grignard or sodium derivatives of the transition metal moieties. The new compounds were characterized by elemental analyses, IR, 1H-, 13C- and
第一全锡-树状大分子Sn [(CH 2)4 SnPh 3 ] 4(2)的合成是由四(丁-3-烯基)锡烷(1)与氢化三苯锡完全氢化而成的。用无水HCl从2的每个树枝中选择性裂解一个苯基,得到Sn [(CH 2)4 Sn(Cl)Ph 2 ] 4(3),在用LiAlH 4处理时会生成相应的氢化物衍生物Sn [(CH 2)4 Sn(H)Ph 2 ] 4(4)包含四个反应性Sn-H键。环戊二烯基衍生物Sn [(CH 2)4 Sn(C 5 H 5)Ph 2 ] 4(5)以及过渡金属取代的衍生物Sn [(CH 2)4 Sn Co(CO)4 } Ph 2 ] 4(6),Sn [(CH 2)4 Sn Fe(CO)2 C 5 H 5 } Ph 2 ] 4(7)和Sn [(CH 2)4 Sn Mn(CO)5 } Ph 2 ] 4(8)已通过将3与过渡金属部分的适当格利雅(Grignard)或钠衍生物偶联而制备。通过元素分析,IR,1
