1,1-Bis(tert-butylamido)-3,3,5,5-tetraphenylcyclotrisiloxane

Abstract

The title compound, C32H40N2O3Si3 or (Ph2SiO)(2)OSi(NH-Bu-t)(2), was synthesized by the in situ reaction of [Ph2Si(OH)](2)O with two equivalents of (BuLi)-Bu-n, followed by the addition of Cl2Si(NH-Bu-t)(2). The addition of tert-butylamide substituents to one of the Si centres causes a slight distortion of the planar cyclotrisiloxane ring.
