Therefore, research on the synthesis of  hexamethyl disilane is mainly focused on the process of reducing coupling trimethyl chlorosilane (TMSCl) by alkali metal. Especially, relatively high yield of hexamethyl disilane can be obtained by reducing coupling TMSCl with metallic Li, which can be attributed to the partial covalent properties of the formed Li salt, and the relatively high solubility of Li salt will contribute to the easy formation of product hexamethyl disilane.

While research on the reduction with K or Na-K alloy is relatively rare due to the potential danger of active metallic K. Hexamethyl disilane has been prepared by using cheap Na and TMSCl as the substrates in this paper. Effects of various factors on the coupling yield were studied systematically, some factors were selected for orthotest to afford the optimal reaction conditions.

And the study of reduce with the use of sodium or sodium-potassium alloy is relatively low, mainly due to potassium is too lively, also there are some dangerous when used. In this paper, a choice of cheap sodium and chlorotrimethylsilane reaction of the hexamethyl-Disilane, in the process of synthesis, a system of coupled reaction of various factors on the impact of yield, and filter out.............experiment, which select the best of conditions.
