CURABLE SILICONE RESIN COMPOSITION AND REACTIVE SILICON COMPOUNDS

A curable silicone resin composition comprises (A) an uncured silicone resin having units of the formula (R*)a(R)bSiO(4-a-b)/2, where each R* is a functional group capable of reacting with Si-OH and/or Si-alkoxy groups and each R is a nonfunctional monovalent hydrocarbon group, a+b is from 1.0 to 3.0 and each molecule of uncured silicone resin contains an average of at least two groups R*, and (B) a silanol or hydrolysable compound of the formula (I) where R' represents a hydroxyl group or a hydrolysable group; each R'' represents hydrogen, a monovalent hydrocarbon which optionally is substituted, or a group within the above definition of R'; and Ar is a substantially nonflexible linkage including at least one para-arylene moiety, so that the groups (R')2R''Si- are spatially separated.

Rigid rod molecules containing two Si(OMe)3 or SiMe(OMe)2 groups for hybrid materials synthesis

The synthesis of new bis(trimethoxysilyl) and bis(dimethoxymethylsilyl)arene compounds containing rigid organic groups such as stilbenyl, diphenylacetylene or diphenylbut-1,3-diyne is reported. The Heck type reaction constituted a convenient route to these compounds, since this coupling reaction appeared compatible with the presence of Si(OR)3 groups.
