The present invention relates to an alkoxysilyl compound having two or more alkoxysilyl groups (hereinafter, referred to as ″alkoxysilyl compound″) showing an excellent heat-resistance in a composite, a composition and a cured product comprising the same, an use thereof, and a method for preparing the alkoxysilyl compound. The alkoxysilyl composition comprising the novel alkoxysilyl compound, according to the present invention, in a composite, shows improved heat-resistance, i.e., an effect of decreasing CTE of the alkoxysilyl composition, or an effect of increasing glass transition temperature or not showing glass transition temperature (hereinafter, referred to as ″Tg less″) by forming a chemical bond between the alkoxysilyl group and a filler (fibers and/or particles). Further, the cured product comprising the alkoxysilyl compound according to the present invention shows an excellent flame retardant property due to the alkoxysilyl group. Moreover, when the alkoxysilyl composition according to the present invention is applied to a metal film of a substrate, an excellent adhesion to the metal film is exhibited due to a chemical bond between a functional group on a surface of the metal film and the alkoxysilyl group.

- Understanding the reactivity of enol ether radical cations: Investigation of anodic four-membered carbon ring formation
-
The reactivity of enol ether radical cations was investigated in anodic four-membered carbon ring formations, advancing the mechanistic understanding of these reactions. The mono-ring-containing aromatic cations were reduced through inter- or intramolecular electron transfer to give mono- or bis-ring-containing compounds, respectively. Small structural changes in the hydrocarbon linkers tethering two aromatic rings exerted a powerful effect on the efficiency of such electron transfer events.

- Selective O-allylation of bisphenol A: Toward a chloride-free route for epoxy resins
-
The O-allylation of bisphenol A (BPA) has been performed with the most selective catalysts for O-allylation of phenols reported previously. Both the cyclopentadienyl-ruthenium catalysts and the palladium-diphosphine catalysts are capable of selectively performing single and double O-allylation of BPA. An intriguing solvent effect is observed; the choice of the solvent is of key importance for both conversion and selectivity. The use of an excess of diallyl ether as allylating agent results in relatively high yields of the bisallyl ether of bisphenol A, while maintaining the high selectivity for O-allylation.
