An aminosilane of the formula: where R1is a linear or branched C1-22alkyl or C3-22cycloalkyl, which may be substituted with at least one halogen atom; R2is a bis(linear or branched C1-22alkyl or C3-22cycloalkyl)amino, a substituted piperidinyl, a substituted pyrrolidinyl, decahydroquinolinyl, 1,2,3,4-tetrahydroquinolinyl or 1,2,3,4-tetrahydroisoquinolinyl, with the substituent selected from the group consisting of C1-8alkyl, phenyl, C1-8linear or branched alkylsubstituted phenyl and trimethylsilyl, with the proviso that when the substituent is C1-8alkyl, there must be at least two such substituent groups present and R1must contain halogen; and R3is a linear or branched C1-8alkyl or C3-8cycloalkyl. The aminosilane may be reacted with an aluminum-alkyl compound and a solid component comprising a titanium compound having at least one titanium-halogen bond and an electron donor, both supported on an activated anhydrous magnesium dihalide, to form a catalyst for polymerization of olefins.

α,α′-Di(trimethylsilylmethyl)amines undergo sequential double desilylation processes, by two-electron oxidation initiated either by photoinduced electron transfer (PET) or Ag(I)F, to produce non-stabilized azomethine ylides efficiently which upon trapping with appropriate dipolarophiles give the corresponding pyrrolidines. Application of this strategy to cyclic analogue for the rapid construction of biologically important 1-azabicyclo[m,3.0]alkane framework is discussed.
Ag(I)F as one electron oxidant for promoting sequential double desilylation : An ideal approach to non-stabilized azomethine ylides for the rapid construction of 1-azabicyclo (m:3:0) alkanes

A novel methodology for effecting sequential double desilylation by Ag(I)F for the generation of non-stabilized azomethine ylide and its application for the synthesis of 1-azabicyclo(m.3.0) alkane systems are described.
