1. Obtenção e caracterização de materiais hibridos organo-inorganicos a base de silsesquioxanos em ponte
In this work, organic-inorganic hybrid materiaIs were prepared through an organic component and an alkoxysilane properly functionalized, by the sol-gel process, at room temperature. Dibutyltin dilaurate was used as catalyst of the silane s hydrolyze/condensation reactions. These materiaIs were obtained from the stechiometric mixture of epoxy resin poly(bisph

2. Estudo da interação de compostos organossilanos com As4 e complexos de metais de transição
The reactions of tetramesithyldisilene with As4 and of 1,1,2.2-tetramethyl-1.2-bis(phenylethynil)disilane with transition metal complexes were studied. Tetramesithyldisilene reacted with As4 to give a remarkable mixture of arsadisilacyclopropyltriarsadisilabyciclopentane [As4Si4Me8] 19, and diarsadisilabicyclobutane [As2Si2Mes4] 20, as well as small amounts
