Abstract
Four new compounds [Sin02.5nJ](Si(CH3)2Y)n n = 8,10; Y = -CHCH2, -CH2Cl, were synthesized and characterized. The synthesis involved the use of the adducts (H3C)3NO.ClSi(CH3)2Y (Y = -CHCH2, -CH2Cl) as reagents to convert the [dbnd]Si-H groups in the hydridospherosiloxanes, HnSin01.5n (n=8,10), directly to [dbnd]SiOSi(CH3)2Y (Y[dbnd]-CHCH2, -CH2Cl) groups. These compounds are polyhedral, polyreactive oligomers consisting of a spherosilicate core, [Sin02.5n], of cubic (n=8) or pentagonal prismatic (n=10) symmetry with reactive functional groups, either vinyl or chloromethyl, attached to each vertex.Keywords
