Summary

Considering the stable compound Me3GeSiCi3 (1) as a potential nucleophile-induced source of SiCl2 moieties and to evaluate the properties of Me2Ge(SiCl3)2 as nucleophile-induced source of SiCh and GeMe2 moieties that could be generated by a kind of a domino-α-elimination, alkylidenediphosphane 5 (Me3Si)2C[DOUBLE BOND]P-PRR' (R = tBu, R' = iPr) was chosen as a new multifunctional trapping reagent for six-electron species SiCl2 and GeMe2. Reaction of 1 with 5 leads to the formation of a stable 2-phospha-1,3-disiletane-ring system. This observation indicates that trichlorosilylgermanes will be of importance as sources of generation of nucleophile-stabilized dichlorosilylene under very mild conditions.
