N-(Trialkylsilyl)allylamines can be deprotonated at the cis-vinylic position to yield 3,N-dilithio-N-(trialkylsilyl)allylamines under mild conditions. N-(Trialkylsilyl)allylamines with terminal alkyl substituents were reported not to form dianions under the same conditions. During our investigations we found that N-(tert-butyldimethylsilyl)-2-buten-1-amine (1) is deprotonated under the reaction conditions
