Treatment of cyclotrisilane 1 with pyridinium bromide yields siliconium bromide 8a. In contrast, 1 reacts with six equivalents of AlMe3 as Lewis acid via an initial complex 13 to silane 10. Reaction of 1 with only three equivalents of AlMe3 forms 12, which is also obtained upon treatment of 10 with quinuclidine or 1. No analogous insertion reaction occurs with BH3, in which case the stable complexed cyclotrisilane 15 is formed.
