EPOXY COMPOUND HAVING ALKOXY SILYL GROUP, COMPOSITION COMPRISING SAME, CURED PRODUCT, USE THEREOF AND METHOD FOR PREPARING EPOXY COMPOUND HAVING ALKOXY SILYL GROUP

The present invention relates to an alkoxy silyl-based epoxy compound exhibiting excellent heat resistant characteristics in a composite, and more particularly, exhibiting a low coefficient of thermal expansion (CTE) and the effect of significantly increasing the glass transition temperature in a composite and eliminating the necessity of a separate silane coupling agent. The present invention also relates to a composition comprising the compound, to a cured product thereof, to the use thereof and to a method for preparing an epoxy compound comprising an alkoxy silyl group. Thus, according to the present invention, provided are an epoxy compound comprising an epoxy group and an alkoxy silyl group, a composition comprising the epoxy compound and a curing agent, a filler and/or a reaction catalyst, a cured product thereof and the use thereof such as in an electronic component or the like. The epoxy composition comprising an epoxy compound having a novel alkoxy silyl group according to the present invention is obtained by a chemical bond resulting from a chemical reaction between the alkoxy silyl group and a filler (fiber and/or particle) and a chemical reaction between alkoxy silyl groups in a composite and/or a cured product, thus exhibiting effects of improved heat resistant characteristics, that is, a lower CTE and a higher glass transition temperature or no glass transition temperature (hereinafter, referred to as 'Tg-less') in an epoxy composite. Furthermore, the cured product comprising an epoxy compound having an alkoxy silyl group according to the present invention exhibits excellent flame resistance by introducing the alkoxy silyl group thereto.

A new method for the facile synthesis of hydroxylated flavones by using allyl protection

The iodine-induced oxidative cyclization of 2′-hydroxychalcones provides a simple, highly efficient approach to various hydroxy flavones and analogues. This process is run under mild conditions, tolerates various functional groups, and provides hydroxy flavones in good to excellent yield. The allyl-protected acetophenones and benzaldehydes were smoothly deallylated under similar conditions.

Rapid and selective deallylation of allyl ethers and esters using iodine in polyethylene glycol-400

A simple and selective deallylation of allyl ethers and esters using iodine (10 mol%) in polyethylene glycol-400 as a green reaction solvent is described. The reaction was performed at room temperature with various aryl/alkyl allyl ethers and esters in go

SnCl2 mediated efficient N,N-dialkylation of azides to tertiary-amine via potential stannaimine intermediate

A base free one-pot conversion of azides to N,N-dialkylamine is described. A two-step reaction pathway has been postulated invoking the intermediacy of stannaimine. This new carbon-nitrogen bond formation strategy adds to the repertoire of tin(II) chemistry.

Allylation of Alcohols and Carboxylic Acids with Allyl Acetate Catalyzed by [Ir(cod)2]+BF4- Complex

A facile method for the synthesis of allyl alkyl ethers from alcohols with allyl acetate was developed by the use of [Ir(cod)2] +BF4- complex. For instance, the reaction of allyl acetate with n-octyl alcohol in the presence of a catalytic amount of [Ir(cod)2]+BF4- complex afforded allyl octyl ether in quantitative yield. Allyl carboxylates were also prepared by the exchange reaction between carboxylic acids and allyl acetate in good yields. The [Ir(cod)2]+BF4- complex catalyzed the reaction of alkyl and aromatic amines with allyl acetate to lead to the corresponding allylamines in fair to good yields.
