The hydrosilylation reaction of diphenylsilane and phthalaldehyde is catalyzed by heteroscorpionate zinc hydride complex LZnH (1, L = ( Pz) CP(Ph) NPh, Pz = 3,5-dimethylpyrazolyl). Both terephthalaldehyde (tPAA) and isophthalaldehyde (iPAA) affords linear polymer; however, when PAA is used, a seven-membered cyclic silyl ether is formed. These products are characterized by H and C NMR spectra. Other properties of polymers are determined by gel permeation chromatography (GPC)-multiangle laser-light scattering, differential scanning calorimetry, and thermogravimetry.
二苯基硅烷和邻苯二醛的硅氢加成反应由异恶唑啉配体锌氢化物络合物 LZnH（1，L = (Pz)CP(Ph)NPh，Pz = 3,5-二甲基吡唑基）催化。邻苯二甲醛（tPAA）和间苯二甲醛（iPAA）都得到线性聚合物；然而，当使用对苯二甲醛时，形成了一个七元环状硅醚。这些产物的结构通过 1 H 和 13 C NMR 光谱进行了表征。聚合物的其他性能通过凝胶渗透色谱（GPC）-多角度激光散射、差示扫描量热法和热重分析进行了测定。
