  A series of heteroleptic scandium SALEN complexes, [(SALEN)Sc(µ-Cl)]2 and (SALEN)Sc[N(SiHMe2)2] is obtained via amine elimination reactions using [Sc(NiPr2)2(µ-Cl)(THF)]2 and Sc[N(SiHMe2)2]3(THF) as metal precursors, respectively. H2SALEN ligand precursors comprising H2Salen [(1,2-ethandiyl)bis(nitrilomethylidyne)bis(2,4-di-tert-butyl)phenol], H2Salpren [(2,2-dimethylpropanediyl)bis(nitrilomethylidyne)bis(2,4-di-tert-butyl)phenol], H2Salcyc [(1R,2R)-(−)-1,2-cyclohexanediyl)bis(nitrilomethylidyne)bis(2,4-di-tert-butyl)phenol] and H2Salphen [((1S,2S)-(−)-1,2-diphenylethandiyl)bis(nitrilomethylidyne)bis(2,4-di-tert-butyl)phenol] are selected according to solubility and ligand backbone variation (“N–(R)–N” bite angle) criteria. Consideration is given to the feasibility of [Cl → NR2] and [N(SiHMe2)2 → OSiR3] secondary ligand exchange reactions. X-ray crystal structure analyses of donor-free (Salpren)Sc(NiPr2), (R,R)-(Salcyc)Sc[N(SiHMe2)2], (Salen)Sc(OSitBuPh2) and (Salphen)Sc(OSiHtBu2) reveal (i) a very short Sc–N bond distance of 2.000(3) Å, (ii) weak β(Si–H)amido–Sc agostic interactions and (iii) an exclusive intramolecularly tetradentate and intrinsically bent coordination mode of the SALEN ligands with ∠(Ph,Ph) dihedral angles and Sc–[N2O2] distances in the 124.27(9)–127.7(3)° and 0.638(1)–0.688(1) Å range, respectively.

  Periodic mesoporous ethylenesilicas with hexagonal P6mm and cubic Fm3m/Pm3n symmetry were prepared by using divalent surfactant C16–3–1 and binary surfactant mixtures C18–3–1 and C18TABr as structure-directing agents, respectively, under basic conditions. A tetramethyldisilazane-based surface silylation was carried out under mild conditions affording hybrid materials SiHMe2@PMO[MCM-41], SiHMe2@PMO[KIT-5] and SiHMe2@PMO[SBA-1], corresponding to silanol group populations of ca. 1.46, 0.67 and 1.63 mmol g−1, respectively. New molecular zinc precursor compounds Zn[N(SiHMe2)2]2 and EtZn(OSiHtBu2) were synthesized via salt metathesis and alkane elimination procedures from ZnCl2 and LiN[SiH(CH3)2]2, HOSiHtBu2 and ZnEt2, respectively. Organozinc and organoyttrium complexes were reacted with the surface silanol groups according to a heterogeneously performed silylamide route, aswell as an alkane elimination reaction, yielding Zn[N(SiHMe2)2]@PMO[MCM-41], Zn[N(SiHMe2)2]@PMO[KIT-5], Zn[N(SiHMe2)2]@PMO[SBA-1], Zn[N(SiMe3)2]@PMO[MCM-41], Zn[N(SiMe3)2]@PMO[KIT-5], Zn[N(SiMe3)2]@PMO[SBA-1], Y[N(SiHMe2)2]x(THF)y@PMO[MCM-41], Y[N(SiHMe2)2]x(THF)y@PMO[KIT-5], Y[N(SiHMe2)2]x(THF)y@PMO[SBA-1] and Zn(OSiHtBu2)@PMO[MCM-41]. The metal loading mainly depended on the surface silanol group population, size and shape of metal-coordinated ligand, and reaction time as shown for Zn contents in the range of 4.2 to 10.6 wt%. In addition, a preferred N(SiHMe2)2/OC6H2tBu2-2,6-Me-4 ligand exchangeability was found for the large yttrium surface centres. The parent and functionalized materials were characterized by powder X-ray diffraction, elemental analysis, N2 physisorption, FTIR, 13C CP and 1H MAS NMR spectroscopy.
