由二氯二苯基硅烷与锂在四氢呋喃中的反应获得的全苯基化的环硅烷之一（先前提出为十二苯基环己硅烷）已显示为十苯基-环戊硅烷。该环硅烷被溴在苯中和锂在四氢呋喃中相当特异地裂解，以高产率得到相应的1，5-二取代衍生物。用三种不同的方法测定了十苯基环戊硅烷的分子量，结果与本文的建议一致。
One of the perphenylated cyclosilanes obtained from the reaction of dichlorodiphenylsilane with lithium in tetrahydrofuran, previously proposed to be dodecaphenylcyclohexasilane, has been shown to be decaphenyl-cyclopentasilane. This cyclosilane is cleaved fairly specifically by bromine in benzene and by lithium in tetra-hydrofuran to give the respective 1, 5-disubstituted derivatives in high yields. Molecular weight determinations on decaphenylcyclopentasilane by three different methods give results which are consistent with the present proposal.
