The first fully characterized protected trisilane has been synthesized in 1998[1] and several derivatives have been investigated since.[2] Most of the latter were used for ring closure reactions with the exception the 1,3-dimethylated-2,2-dihalogenated species. [3] Some very interesting derivatives remain undiscovered, especially the 1,3-dihydrido, 1,3-dichlorido and 1,3-diphosphino silanes.
Similar to their carbon analogues, the diphosphinotrisilanes are expected to offer a wide range of uses in metalorganic synthesis and complex chemistry due to the well-known electron donating properties of phosphorus. The few established, stable diphosphasilane derivatives are compounds of the type (R2P-SiMe2-)2.[4] Other diphosphasilanes with backbone lengths of three or more silicon atoms remain, with exception of Me2Si[-Me2Si-PPh2]2,[5] unexplored.
The aim of this work is the preparation of silane chains whose backbone consists of three silicon atoms and their functionalization to the so far unknown dihydrido, dichlorido, and diphosphino derivatives. Furthermore, the focus is on the characterization of the compounds obtained by NMR spectroscopy, single crystal X-ray investigations and melting point determinations. The experimental characterization was supported by DFT calculations
