标题:Reaction Of Organylchlorosilanes With Dimethyl Sulfoxide In The Presence Of octamethyltrisiloxane
摘要:Dichloro(Methyl)(Vinyl)Silane Reacts With Dmso In The Presence Of octamethyltrisiloxane To Form Cyclooligomethyl(Vinyl)Siloxanes(Mevisio)(N) (N = 3-6). The Reaction Involves Disproportionation Of octamethyltrisiloxane Into Hexamethyldisiloxane And Decamethyltetrasiloxane. Along With The Latter Two Products,Insertion Products Of Methyl Vinyl Silanone Into Both Permethyloligosiloxanes Were Identified. Alkyltrichlorosilanes Rsicl3 (R = Me,Et) React With Dmso In The Presence Of octamethyltrisiloxane To Form Cyclic Oligoalkyltrichlorosiloxanes (Rcisio)(M) (M = 3-6).
