摘要

The cyclic boratrisiloxanes (PhBO)(RR'Si0) 2 (1, R= R'= Me; 2, R= Me, R'= Ph; 3, R= R'= Ph) have been prepared via the reaction of the dichlorodisiloxanes 1, 3-C1RR'SiOSiRR'Cl with phenylboric acid in the presence of NEt3 as an HCl acceptor. Similar procedures using the appropriate a, o-dichlorosiloxanes CIMe2Si (OSiMe2),, OSiMe2Cl (n= 1 or 2) afforded the boracyclotetrasiloxane (PhBO)(MezSiO) s (4) and the boracyclopentasiloxane (PhBO)( ...
