The hydrosilylation reaction of
diphenylsilane
and phthalaldehyde is catalyzed by heteroscorpionate zinc hydride complex LZnH (1, L = (
Me

2
CP(Ph)

NPh,
Me
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
1
H and
13
C NMR spectra. Other properties of polymers are determined by gel permeation chromatography (GPC)-multiangle laser-light scattering, differential scanning calorimetry, and thermogravimetry.
