The chemistry of the SiH bond with acid treated clays

Abstract The reaction of 1,1,3,3-tetramethyldisiloxane (M H M H ) with acid treated clays (Filtrol) gives a mixture of HSiMe 2 O-(M H ) stopped fluids, cyclic (Me 2 SiO) n oligomers and gaseous products which include H 2 and Me 2 SiH 2 . The reaction does not proceed with strong acid alone or with acid neutral clay.

Synthesis of Silicon Containing Benzaldehydes and Conversion to Schiff's Bases

Abstract Synthesis of the first silicon substituted benzaldehyde derivatives is described. Reduction of tetramethyldiphenyldisiloxane-4,4′-dicarboxylic acid chloride with tri-t-butoxylithiumaluminum hydride gives tetramethyldiphenyl-disiloxane-4,4′-dicarboxyaldehyde in 40% yield. Synthesis and characterization of Schiffs base derivatives are described.
