 Title    Synthesis and Molecular Structure of Silylated Ethenes and Acetylenes  
 Abstract    Disilylacetylene (1) has been obtained from LiA lH 4 reduction of bis(trichlorosilyl)ace-tylene (2) and bis[(trifluoromethylsulfonyloxy)silyl]acetylene (4). The catalytic hydrosilyl-ation of 2 with HSiCl3 affords tris(trichlorosilyl)ethene (5) and l.l,2-tris(trichlorosilyl)ethane (6). The synthesis of 6, fra/«-bis(trichlorosilyl)ethene (8) and l,l-bis(trichlorosilyl)ethene (9) has been accomplished by hydrosilylation of trichlorosilylacetylene (7) which was synthesized by the reaction of trichloro(trifluoromethylsulfonyloxy)silane with sodium acetylide.

 Title    Metallkomplexe in Anorganischen Matrices, 5 [1] Katalytische Silanoxidation an einem heterogenisierten Rhodium-Komplex M etal Complexes in Inorganic Matrices, 5 [1] Catalytic Silane Oxidation at a Heterogenized Rhodium Complex  
 Abstract    A heterogenized rhodium complex, prepared by sol-gel processing of Rh(CO)Cl[PPh2C H 2C H 2Si(OEt)3]2 and Si(OEt)4, is shown to catalyze the conversion of the si­ lanes H4_"SiPh" (n = 1 -3) or (H M e2Si)20 to (poly)siloxanes by air or water. Using T H F as a solvent, the silanoles Ph3SiOH or Ph2Si(OH)2 are obtained instead. The reaction of phenyl-acetic acid or acetic acid with HSiPh3 to give silyl esters is catalyzed by the same com pound.
