Facile Synthesis of π‑Conjugated Quinazoline-Substituted Ethenes from 2‑Ethynylanilines and Benzonitriles under Transition-Metal-Free Conditions

A new
transition-metal-free version for the synthesis of π-conjugated
quinazoline-substituted ethene derivatives from readily available
starting materials has been developed. Quinazoline-substituted ethenes
were obtained in moderate to high yields with completely Z-selectivity, and the resulting quinazoline-substituted ethenes show
typical aggregation-induced emission (AIE) properties.
