Tetraaminoethylene

Tetraaminoethylene organic compounds of the generla chemical formula: (R2N)2C=C(NR2)2.

Chemistry of tetraaminoethylene

 * These compounds can be formed in the dimerisation reaction of stable diaminocarbenes, a type of stable carbene.


 * Tetraaminoethylenes react with acids to give formamidinium salts.


 * Tetraaminoethylenes react with oxygen to given ureas (R2N)2C=O, with the bis-tetramethyl example (Me2N)2C=C(NMe2)2 emitting a green-blue light upon reaction, and was used by the downed US navy pilots to signal for help in World War II.
