%X Some reactions of octaisopropylpentacyclo(9,5,1,13,9,15,15,1 7,18)octasiloxane (octaisopropyl-T8) and its brominated derivatives have been investigated. The isolation of compounds (C8H6Br)n(C3H7)8-n(SiO1.5)8 (n = 1, 2, or 3) is reported. Dehydrobromination of &#945;-brominated octaisopropyl-T8 compounds yields isopropenyl-T8 derivatives. Bromine addition to the latter occurs. The high resolution p.m.r. spectra of octaisopropyl-T8 derivatives are discussed.
