“…This compares to pKb values of 2.9-3.4 for simple aliphatic trialkylamines and 7.2-8.8 for simple pyridines (12). Despite the reputation of DBU and DBN as strongly basic yet non-nucleophilic reagents (9, lo), a number of recent reports have shown that these bases can indeed act as nucleophiles (13), notably towards halogenated derivatives of main group elements (14), and a few DBU-metal complexes have recently been reported (15).…”

“…Die Bindung zwischen C3–N1 weist eine ähnliche Länge mit 1.347(6) Å auf. Beide Bindungslängen sind somit kürzer als die einer Kohlenstoff‐Stickstoffeinfachbindung und sind vergleichbar mit den C–N‐Bindungslängen, die unter anderen in trans ‐[Rh(CO)(DBU)(PPh 3 ) 2 ]ClO 4 18 und [ tert ‐Butyl α‐Cyanoacetate][DBU‐H] 19 im DBU‐Rest gefunden worden sind. Bei [DBU‐H] + ist jedoch die C3–N2‐Bindung unwesentlich länger (1.322(2) Å) als die Bindung zwischen C3–N1 (1.310(3) Å).…”
