| TETRAKIS(DIMETHYLAMINO)ETHYLENE Usage And Synthesis |
| Chemical Properties | light yellow-green liquid with an unpleasant | | Uses | Involved in TDAE methodology for coupling and intramolecular Buchwald reactionsActs as a reducing agentReactant involved in:- Dioxygenation
- Insertion of aluminum anion into the C-N bond
- Chemiluminescent reactions with oxygen
| | Purification Methods | Impurities include tetramethylurea, dimethylamine, tetramethylethanediamine and tetramethyloxamide. It is washed with water while being flushed with nitrogen to remove dimethylamine, dried over molecular sieves, then passed through a silica gel column (previously activated at 400o) under nitrogen. De-gas it in a vacuum line by distillation from a trap at 50o to one at -70o. Finally, it is stirred over sodium-potassium alloy for several days. [Holroyd et al.
