Green chemistry

Aspects in chemistry are considered to be greeen
- reduce and prevent pollution at its sources
-design produces and process that minimized the use and generation of hazardous substances.
- better to prevent wash then clean it up
- use and generated substances that are little or not toxic to health and environment.
- minimize us of auxiliary substances eg solvents sustainable ones if needed. water/ DCM
- low energy consumption, reaction at room temperature, and ambient pressure.
- reusable
- reduce derivative, no protecting groups few steps as possible.
- catalytic reagents are superior to stroimometric
- products should be degraded into harmless products
