  摘要：

  应变或被两个以上氟原子取代的硅键很容易在室温或室温以下被分子氧和双-（三甲基甲硅烷基）过氧化物（BSPO）氧化，主要形成相应的二硅氧烷。前者的有氧氧化被2,4,6-三（叔丁基）苯酚抑制，而后者则不受抑制。还描述了用BSPO氧化SiH键和制备三种新的（氟）甲基乙硅烷的方法。

  Five new permethylated linear polysilanes of the formula CH3[Si(CH3)2]nCH3, where n is equal to 8, 9, 10, 11 and 12, have been prepared from the co-condensation of appropriate chlorosilanes using sodium-potassium alloy as condensing agent in a benzene-ligroin or benzene-n-heptane mixture. These compounds are all white crystalline substances. The melting points display a regular progression as the number

  Silylation of allylic acetates (1) using organodisilanes (2) was carried out in the presence of a catalytic amount of Pd(DBA)2-LiCl at 100 degrees C. The silylation proceeded smoothly without beta-hydrogen elimination of. resulting (pi-allyl)palladium intermediate. The added chloride salt such as LiCl or NaCl was indispensable for the catalytic activity. On the other hand, remarkable improvement of the silylation was realized by employing allylic trifluoroacetates (4) in place of the acetates (1) as the substrates. The silylation proceeded even at room temperature, and the added chloride salts was not necessary as the catalyst component. In the silylation, transmetalation of the disilanes (2) with (eta(3)-allyl)palladium intermediate (7) might be a critical step in the catalytic cycle. Model reactions for the transmetalation were carried out.
• 1,4-Carbosilylation of 1,3-Dienes via Palladium Catalyzed Three-Component Coupling Reaction

  Three-component coupling reaction of acid chlorides, organodisilanes, and 1,3-dienes achieves 1,4-carbosilylation of the 1,3-dienes to afford allylic silanes as the product. Bis(dibenzylideneacetone)palladium, a naked Pd(0) complex without donating ligand, showed high catalytic activity. A carbon and a silicon substituent are introduced at 1- and 4-positions of the 1,3-dienes regio- and stereoselectively with concomitant decarbonylation of the acid chlorides. A wide variety of allylic silanes are synthesized in high yields from these easily accessible substrates. On the other hand, a bully acid chloride such as adamantane-1-carboxylic acid chloride did not undergo the decarbonylation reaction but afforded allylic silanes containing acyl functionality. In all these reactions, transmetalation of the disilanes with eta(3)-allylchloropalladium intermediates might be a critical step in the catalytic cycle. As a model reaction for the transmetalation, reaction of di-mu-chlorobis[(1,2,3-eta)-4-phenyl-2-butenyl]dipalladium with disilanes was carried out. Although intermediate eta(3)-allylsilylpalladium species could not be detected, the corresponding allylic silanes, silyl chlorides, and Pd(0) metal were formed during the reaction. Furthermore, a similar three-component coupling reaction using aryl iodides, organosilylstannanes, and dienes also proceeded. However, the selectivity and the yield decreased considerably.
