Method for Producing Acyloxysilanes, Acyloxysilanes Obtained Thereby, and Use of Same
An object of the invention is to provide a method for efficiently producing an acyloxysilane which is useful as a functional chemical, an acyloxysilane obtained thereby, and the use thereof. The present invention provides: a method for producing an acyloxysilane, including a reaction step of reacting an alkoxysilane with a carboxylic anhydride in the presence of a catalyst, wherein the alkoxysilane is a specified alkoxysilane represented by General Formula (I), the carboxylic anhydride is a specified carboxylic acid represented by General Formula (IIA) or (IIB), the catalyst is an acid catalyst, and an acyloxysilane obtained in the reaction step is a specified acyloxysilane represented by General Formula (IIIA) or (IIIB); and the use of the acyloxysilane as a surface treatment agent or the like.

Reaction of Acetoxysilanes with Hydroxy Compounds
Tetraacetoxysilane reacts with hexanol, cyclohexanol, and phenol to give products of complete or partial replacement of the acetoxy groups. The rate of hydrolysis of the SiOR group in alkoxy(phenoxy)-silanes and alkoxy(phenoxy)acetoxysilanes in homogeneous (THF) and heterogeneous media (on cellulose surface) increases in the series c=Si-OC6H5 > =Si-OC6H13 > =Si-OC6H11.

Process for the preparation of di-tert.butoxydiacetoxysilane
Di-tert.butoxydiacetoxysilane is prepared by reacting tetraacetoxysilane with tert.butanol at a reaction temperature of up to 60° C., and the resulting di-tert.butoxydiacetoxysilane is isolated.

Structural investiagations of zirconium tetra-acetate and the group IVB tetra-acetates
Solid-state i.r., Raman 1H and 13C NMR spectra are reported for solid zirconium tetra-acetate and for the group IVB tetra-acetates (M=Si, Ge, Sn or Pb).The types of acetate co-ordination have been identified: Zr(OAc)4 has a polymeric eight-co-ordinate structure and contains both bridging and bidentate acetate groups; Si(OAc)4 and Ge(OAc)4 contain only unidentate acetates to give four-co-ordinate structures while Sn(OAc)4 and Pb(OAc)4 contain only bidentate acetate groups to give eight-co-ordinate monomeric structures.The solid-state Raman 13C NMR spectra are reported for the first time.

Mixed Ligand Complexes of Si(IV) with 2-Methylpentane-2,4-diol and Schiff Bases
Synthesis and characterization of mixed ligand complexes of silicon of the type Si(OAc)(C6H12O2)(SB), Si(C6H12O2)(SB)2, Si(C6H12O2)(S'B') and SI(C6H12O2)(S''B'') with 2-methylpentane-2,4-diol and monobasic bidentate (SB(-)), bibasic tri-(S'B'(2-)) and tetradentate (S''B''(2-)) schiff base anions are reported.All the complexes are monomeric, yellow in colour with sharp melting points.The derivatives have been characterized on the basis of elemental analyses, conductivity measurements and IR as well as PMR spectral data.
