Sažetak
The linkage of two P2-phosphazenyl groups through a C2-symmetric (R, R)-1, 2-diaminocyclohexane (DACH) backbone yielded the new chiral superbases DACHP2NMe2 and DACH-P2Pyr (Pyr=pyrrolidinyl). These bases were prepared by a Kirsanov reaction and studied with respect to their spectroscopic and structural characteristics. Theoretical calculations concerning their basicity properties revealed remarkable pKBH + values of 38.1 and 39.9 on the acetonitrile scale ; this makes them the strongest nonionic chiral superbases known to date.
