Reversible [4 + 2] cycloaddition reaction of 1,3,2,5-diazadiborinine with ethylene

, 2015
Under ambient conditions, a [4 + 2] cycloaddition reaction of 1,3,2,5-diazadiborinine 1 with ethylene afforded a bicyclo[2.2.2] derivative 2, which was structurally characterized. The cyclization process was found to be reversible, and thus retro-[4 + 2]

Highly Regioselective 1,3-Dipolar Cycloaddition of Nitrilimines and Thioaurones Towards Spiro-2-Pyrazolines: Synthesis, Characterization, and Mechanistic Study

Reactions
In this paper, we report a highly regioselective 1,3-dipolar cycloaddition (1,3-DC) reaction of nitrilimines with thioaurone derivatives that afforded the hitherto unreported spiropyrazolines. Spectroscopic and spectrometric data were utilized to confirm
