Abstract

The new cyclo-diboratetrasiloxanes (RBO) 2 (R′ 2SiO) 2 (R= p-BrC6H4, o-MeC6H4, m- NH2C6H4, m-NO2C6H4, Bun; R′ 2= Ph2, R= Ph, p-BrC6H4, m-NO2C6H4; R′ 2= octn/Me) and cyclo-boratrisiloxanes (RBO)(R′ 2SiO) 2 (R= p-BrC6H4, m-NH2C6H4; R′ 2= Me2, Ph/Me) were prepared in high yield by condensation reactions. cyclo- Diboratetrasiloxane· amine adducts (1: 1) were obtained for (PhBO) 2 (Ph2SiO) 2 with ...
