Rapid cycloaddition of a diazo group with an unstrained dipolarophile
The cycloaddition of a diazoacetamide with ethyl 4,4,4-trifluorocrotonate proceeds with k = 0.1 M(−1)s(−1). This second-order rate constant rivals those of optimized strain-promoted azide– alkyne cycloadditions, even though the reaction does not release strain. The regioselectivity and a computation...
