    Description / Table of Contents: Whereas (CH3)3Si—P(C2H5)2 does not react with LiP(C2H5)2 (I), there are reactions of SiH-containing silylphosphines with one P(C2H5)2 group as well as of SiH- and Simethylated silylphosphines with (I), yielding phosphorylated products and LiH according to equ. (1) (2).SiH-containing Silylphosphines, being Si—CH3-free and having more than one P(C2H5)2-group, such as HSi[P(C2H5)2]3, react with LiP(C2H5)2 by exchange of Li for H, acc. to equ.(3).With (CH3)3SiCl, LiSi[P(C2H5)2]3 yields (CH3)3Si—Si[P(C2H5)2]3 and with SiH3Br H3Si—Si[P(C2H5)2]3.There is a cleavage of the Si—P bond with Li-CH3 or n—LiC4H9.The reaction starts as shown in equ. (4), yielding (CH3)3SiH and (CH3)3Si—P(C2H5)2 as intermediate products and finally (CH3)4Si (equ. 5).
    Notes: Während (CH3)3Si—P(C2H5)2 nicht mit LiP(C2H5)2 (I) reagiert, setzen sich SiH-haltige Silylphosphine mit einer P(C2H5)2-Gruppe sowie SiH- und Si-methylhaltige Silylphosphine mit (I) unter Phosphorylierung und LiH-Bildung um; z. B. SiH-haltige, Si—CH3-freie Silylphosphine mit mehreren P(C2H5)2 Gruppen wie HSi[P(C2H5)2]3 reagieren mit LiP(C2H5)2 unter Austausch von Li gegen H nach. LiSi[P(C2H5)2]3 bildet mit (CH3)3SiCl das (CH3)3Si—Si[P(C2H5)2]3, mit SiH3Br das H3Si—Si[P(C2H5)2]3.LiCH3 bzw. LiC4H9 spalten die Si—P-Bindung. Die Reaktion beginnt nach und führt über (CH3)3SiH, (CH3)3Si—P(C2H5)2 zum Si(CH3)4
