| Abstract: | The synthesis, structures and reactivity of the spirocyclic yttrium and lanthanum disiloxides {(CH2R2SiO)2]2M}H M = Ln, Y; R = SiMe(SiMe3)2] 3 and 4 are reported. Compounds 3 and 4 were prepared from reactions of two equivalents of CH2(R)2SiOH]2 R = Si(SiMe3)2Me] (1) with one equivalent of MN(SiMe3)2]2 (M = Y, La), respectively. |
