The Open-Chained Organosilyl Phosphines, Arsines, Antimonines and Bismuthines

1 The Open-Chained Organosilyl Phosphines, Arsines, Antimonines and Bismuthines 

Organosilylphosphines are usually prepared from an alkaline metal phosphide and a chloroorganosilane [409, 410], e.g. (Eq. 3.211 and 3.212)  

Lithium, sodium and potassium phosphides are used for this reaction. Phosphide excess should be avoided. Yields are high. 

Tris(trimethylsilyljantimonine [412] (80% m.p. — 1 °C) is made from trilithium anti-monide (Eq. 3.214)  

Sodium aluminium tetraphosphide reacts with halohydroorganosilanes in diglyme at -20°C [413] (Eq.3.215)
