Lithium N-Lithiomethyldithiocarbamates: New N-Alkylaminomethyl Anion Equivalents; III.1 2-Imidazolidinethiones and 1, 2-Diamines via Electrophilic Aminoalkylation with Imines and Iminium Salts Treatment of lithium N-butyl-N-lithiomethyldithiocarbamates 3 with various aldimines and ketimines 4 leads to 1,3,4, 4-tetrasubstituted 2-imidazolidinethiones 6. If iminium salts 7 are used as electrophiles, unsymmetrically substituted 1,2-diamines 8 are obtained.
