11. It generates phosphine gas according to the following hydrolysis equation. 12. The production of phosphine gas occurs in only specialized, local conditions. 13. Hydrocyanation and hydrogenation reactions also implement phosphine -mediated catalysts. 14. They behave like phosphine ligands, but are less basic. 15. The use of phenylsilane proceeds with retention of configuration at the phosphine . 16. This bidentate ligand chelates metals via the two phosphine groups. 17. Chiral phosphine ligands can be generally classified as mono-or bidentate. 18. It readily undergoes substitution by tertiary phosphines and other Lewis-bases. 19. On contact with water, calcium phosphide releases phosphine , which ignites spontaneously. 20. A related hypothesis involves the natural chemiluminescence of phosphine .
