I've noticed that dimethyl compounds tend to have extreme reactive, including bioreactive, characteristics.
Am I being misled by anecdotal selection bias, or is this generally true. And if generally true, are there clear theoretical explanations as to why?
Examples that come to mind:
- Dimethyl sulfoxide (DMSO) readily penetrates skin, and can carry lots of things across the skin barrier along with itself.
- Miniscule amounts of dimethyl mercury will not only penetrate skin and many common PPE but are also irreversibly lethal.
- Many dimethyl-metals are pyrophoric (i.e., they auto-ignite in a standard atmosphere).
