(7,10-diphenylfluoranthene-8-)heptamethylcyclotetrasiloxane (DFHMCTS) and (7,10-diphenylfluoranthene-8-) triethoxysilane(DFTES) were synthesized via Diels-Alder reaction of 7,9-diphenyl-8H-cyclopentacena phthylene-8-one (DCPAO) with vinyl-heptamethylcyclotetrasiloxane (VHMCTS) and vinyl-triethoxysilane(VTES) respectively by using diphenylether as solvent. The structures of the two new products have been characterized by IR, UV, (HNMR)-H-1 and elememental analysis.

Flashvacuumpyrolysis (FVP) of 2,7-dimethyl-2,3 : 7,8-diepoxy-5-silaspiro[4.4]-nonane with cyclotetra- or cyclopenta-siloxanes (D4 or D5) leads to products which apparently result from transannular insertion of [OSiO] or an equivalent synthon inti SIO single bonds of D4 or D5: 2,4,6,8,10-pentasila-1,3,5,7,9,11-hexaoxaspiro[5.5]undecane (D2QD2) and 2,4,6,8,10,12-hexasila-1,3,5,7,9,11,13-heptaoxaspiro[5

The heterofunctional condensation of (dihydroxy)organodisiloxanes and -trisiloxanes with vinyl(hydro)organodichlorosilanes was studied with the purpose of preparing alpha,omega-dichloroorganosiloxanes with reactive Si-H and Si-CH=CH2 groups. During the isolation, 1,9-dichloro-1,9-dihydropentamethyloctasiloxane disproportionates with the elimination of (dichloro)methylsilane to form heptamethylcyclotetrasiloxane. A series of cyclotetra-, cyclohexa-, and cyclooctasiloxanes with Si-H and Si-CH=CH2 groups was obtained by the condensation of alpha,omega-dihydroxyorganosiloxanes with alpha,omega-(dichloro)divinyl(dihydro)organosiloxanes.
