摘要：

A study of reaction variables in the coupling of dimethyldichlorosilane with sodium-potassium alloy to form cyclic permethylpolysilanes has been carried out. Recommended procedures are given for the preparation of Me12Si6 and for obtaining maximum amounts of Me10Si5 and Me14Si7. The isolation of Me16Si8 is also described. Permethylpolysilanes have also been obtained by thermal cracking of linear (Me2Si)x polymer, and by base-catalyzed redistribution of linear and cyclic polysilanes. Possible mechanisms for the condensation and redistribution reactions are discussed. © 1969, American Chemical Society. All rights reserved.
