A green and sustainable metal-free, additive-free olefination approach is proposed for the facile synthesis of various unsaturated N-heteroazaarenes from simple methyl-substituted heteroarenes and amines. The developed protocol employs only air as the sole oxidant and provides a useful strategy for obtaining various E-selective conjugated heterocyclic olefins. This provides a useful strategy for application
