Fig. 1.-Cyclic siloxazanes prepared (corners represent silicon with dimethyl substitution except where replacement of one or both methyl groups by phenyl is indicated). expense of low cyclics. In spite of this, reasonably good yields were obtained in some cases. However, none of the four-membered ring cyclics were isolated in reactions of ammonia or amine with dichlorodisiloxanes. In these reactions the eight-membered ring compound was the ...
