The hydrosilylation reaction of diphenylsilane and phthalaldehyde is catalyzed by heteroscorpionate zinc hydride complex LZnH ( 1 , L = ( Me Pz) 2 CP(Ph) 2 NPh, Me Pz = 3,5‐dimethylpyrazolyl). Both terephthalaldehyde ( t PAA) and isophthalaldehyde ( i PAA) 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.
