Phosphorus hydrides lead halides

Of all the reactions studied, only the synthesis of nitrogen oxides and acetylene in arcs or plasma torches and that of ozone in glow and corona discharges are of major importance. In addition, a few small-scale preparations of inorganic compounds have been developed, e.g. synthesis of hydrazine and of hydrides and halides of silicon, germanium, tin, lead, phosphorus or arsenic 3> ... 

Useful carbon nucleophiles are derived from the phosphorus, sulfur and silicon yJ des Jhe elimination of a hydrogen halide from a phos-phonium salt by a strong base, such as sodium hydride, leads to the formation t>f a carbanion (see Scheme 3.47). The carbanion of this ylide is...
