The Ndiazo,C3-diradical of diazomethane (˙NN–H2C˙) is a resonance structure with 1,3-dipole form. And alkyl diazoacetate (ethyl diazoacetate, EDA) can interact with α,β-unsaturated aldehyde (cinnamaldehyde, CA) without any catalyst to compose the Ndiazo,C5- and Ndiazo,C8-diradicals, which are the building species to produce the copolymer of EDA with CA through a sequential series of Ndiazo,Cω-diradical intermediates.
