Scheme 4

Lewis acid‐catalyzed rearrangement of cyclohexasilanes 12 to give silylcyclopentasilanes 13 (a: R1=R2=R3=Me; b: R1=R2=SiMe3, R3=Me; c: R1=R2=R3=SiMe3). Reaction conditions for 12 a: Lewis acid: Ph3C+, solvent: CD2Cl2 or C6D6; for 12 b: Lewis acid: AlCl3, solvent: cyclohexane; for 12 c: Lewis acid: AlCl3, solvent: cyclohexane).14
