Synthesis of a novel exceedingly strong nonionic superbase

Article abstract of DOI:10.1080/10426509708044218

The synthesis of a novel superbase P(HNCH₂CH₂)(i-PrNCH₂CH₂) ₂N, 2a, is discussed. The conditions for the preparation and purification of H₂NCH₂CH₂N(CH₂CH ₂N-i-Pr)₂. 4a, starting from commercially available (H₂NCH₂CH₂)₃N (tren) were optimized. The existence of the novel zwitterion HP(N^-CH₂CH₂)(i-PrNCH₂CH ₂)₂N⁺, 2b, was substantiated by NMR spectroscopy. The Superbase 2a crystallizes from its melt when cooled slowly to -4 °C, and then remains as a solid at room temperature for several days. Hence it can be handled as a liquid or as a solid.
