Other main group elements have been used as promoters in MCS beds containing copper, tin and zinc. Phosphorus and indium have been used in the MCS reaction. The reaction of silicon (40 g) with MeCl (2 bar) at 300 °C in the presence of Cu (3.2 g), ZnO (0.05 g), In (0.004 g) and P (0.056 g) gave 1.7% of Me3SiCl, 0.017% mixture of MeSiCl3/Me2SiCl2 and 3.7% of polysilanes34. Antimony, just below phosphorus in...
