Methylphosphine
Methylphosphine is the simplest organophosphorus compound with the formula CH3PH2, often written MePH2. It is a malodorous gas that condenses to a colorless liquid. It can be produced by methylation of phosphide salts:[1]
- KPH2 + MeI → MePH2 + KI

Reactions
The compound exhibits the properties characteristic of a primary phosphine, i.e., a compound of the type RPH2. It can be oxidized to methylphosphonous acid:
- MePH2 + O2 → MeP(H)O2H
It protonates to give the phosphonium ion:
- MePH2 + H+ → MePH3+
With strong bases, it can be deprotonated to give methylphosphide derivatives:
- MePH2 + KOH → K[MePH] + H2O
gollark: It *isn't* in less gun-y countries like this one.
gollark: I lean somewhat libertarian, so I'd say "guns to anyone who is demonstrated to be reasonably sane and able to handle guns safely and is probably not a criminal".
gollark: Probably somewhat lower. I'm not certain. Addressing the causes of crime is probably generally better than increasingly strict weapons laws.
gollark: The UK seems to have substituted the possible gun crime problem an alternate UK would/might have for a knife crime problem instead.
gollark: High gun murders → states try and implement laws to remove guns.
