Reactions of the alpha,beta-unsaturated alkoxychromium(0) carbenes 1, 2, 5, and 6 with Et3B in THF solution at room temperature, in the presence of oxygen as radical initiator, generate the products derived from 1,4-radical addition. The reaction can be interpreted through the initial formation of the delocalized intermediate radical 11, from which either addition products or a competitive polymerization process are obtained.
