Abstract

A vicelike grip on a proton is exerted by the unusual nonacyclic product 1, which forms spontaneously in a unique enamine trimerization that occurs when azatriquinenamine is heated in the presence of a proton source. pKa measurements and computational modeling of the proton affinity substantiate the superbasic character of the trimer.
