Description

The reaction of organic azides and electron-deficient alkenes was investigated in a deep eutectic solvent. A series of highly substituted 2-pyrazolines was successfully isolated and their formation rationalised by DFT calculations. The critical effect of substitution was also explored; even relatively small changes in the cycloaddition partners led to completely different reaction outcomes and triazolines, triazoles or enaminones can be formed as major products depending on the alkene employed
