Özet

Deprotonation of a 1,1'-bridged bis(1,3-diaikyl-1,4,5,6-tetrahydropyrimidinium) diiodide with NaH gives in high yield a tetraaminoalkene 4, whereas the corresponding non-bridged tetrahydropyrimidinium iodide reacts with NaH only in the presence of KOBu; the title bridged tetraaminoalkene 4f was structurally characterized by single-crystal X-ray diffraction.
