The Preparation and Properties of Some New Nitrogen and Fluorine Derivatives of Disilane

Efficient curing of polymethylsilane by borazine and reaction mechanism study

“…Moreover, increased relative partial pressures of both methylsilane (MeSiH 3 ) and dimethylsilane (Me 2 SiH 2 ) were also identified at the longer reaction time. It is believed that these two silanes were formed by a disproportionation reaction between Si Á/Si and SiÁ/H bonds or by the dehydrocoupling of Si Á/H, as described by Boury et al [9], Ring and coworkers [31,33] and Abedini and McDarmird [35], who observed similar silane byproducts during the treatment of PMS in the presence of other boron derivatives. In this case, the nitrogen detected in the accumulated gaseous species must be from the atmosphere in glove-box where the PMS and borazine samples were charged.…”

“…Boury et al[9] investigated the disproportion of Si Á/Si and Si Á/H reaction in PMS using B[OSi Á/(CH 3 ) 3 ] 3 as a catalyst. Ring et al[33,34] and Abedini et al[35] also studied the…”

Aminoderivate hydrierter Oligosilane: Darstellung, Charakterisierung und Eigenschaften

“…Polysilanylamine entstehen nicht: Erwartungsgem/iB sind sowohl Hydrolyseempfindlichkeit als auch thermische Labilit/it bei den Bis(trimethylsilyl)aminoderivaten 9-11 wesentlich schw~cher ausgepr/igt als bei den Diethylaminopolysilanen 5-8. (HsSiz)aN ist unter Stickstoffbis zu 100 °C stabil, in Proben von (HsSi2)N(CH3) 2 lassen sich bereits nach 48h bei 0°C Zersetzungsprodukte nachweisen [4,5]. Das Arbeiten mit 5-8 hingegen erfordert strengen LuftausschluB, unter Inertgas tritt bereits bei -30°C nach einigen Wochen langsame thermische Zersetzung ein.…”

Synthesis and Properties of 1,2-Dichlorodisilane and 1,1,2-Trichlorodisilane

“…[25] So far, FSi 2 H 5 , [26] F 3 SiSiH 3 , [21,24] F 5 Si 2 H [22] and F 2 HSiSiHF 2 [25] have been synthesised by these procedures. In our group we have focused on the electrophilic cleavage of silicon-aryl bonds by HCl, HBr or HI:…”
