The methylphenylsilanes Ph2Si(SiMe3)2, SiMe3SiPh2SiPh2SiMe3, SiMe3SiPh2SiPh2SiPh2SiMe3, PhSi(SiMe3)3 and (SiMe3)2SiPhSiPh(SiMe3)2 have been prepared by dehalogenation of mixtures of Ph2SiMe2/ClSiMe3 and PhSiCl3/ClSiMe3 with sodium-potassium alloy or by reductive coupling of appropriate triflated silanes with lithium. The reactions of the silanes with HX/AlX3 (X = Cl, Br, I) as well as triflic acid
