Article abstract of DOI:10.1246/cl.1983.1711

The reaction of 1,2-dichlorotetraalkyldisilanes, Cl(R1R2Si)2Cl (R1=R2=iPr; R1, R2=iPr, Me; R1, R2=Me3SiCH2, Me; R1, R2=tBuCH2, Me; R1, R2=tBu, Me), with an excess amount of lithium in tetrahydrofuran gave the corresponding peralkylcyclopolysilanes, n (n=4-5), under mild conditions.
