Reactions of the pentacoordinate aryldioxydihydrosilane Ph(Ar)SiH2 (1) with hydroxyl groups, carbonyl derivatives and PCl5 resulted in formation of new alcoxylated, phenoxylated and halogenated hydrosilanes Ph(ArO)(H)X (X = Cl, OR, OAr, OC(O)R), respectively. Treatment of the hexacoordinated (4+2) diaryloxydihydrosilane (ArO)2SiH2 (2) with N-chloro- or N-bromosuccinimide, trimethylsilyltriflate or iodine yielded the novel stable silicenium ion [(ArO)2(H)Si](1+)X(1-). Reactions of 2 with sulfur S8 and the transition metal complex Fe(CO)5 have resulted in the isolation of the new complexes (ArO)2Si = E [E = S, Fe(CO)4]. Decomposition modes of the tetracoordinate 2,2-diaryloxytrisilane (Me3Si)2Si(OAr)2 (3) on thermolysis and photolysis have also been studied; two pathways involving formation of the two silylenes (ArO)(Me3Si): and (ArO)2Si: have been identified by trapping experiments
