In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Photochemical behavior of halogenoheterocyclic derivatives. The alternative between arylation and dehalogenation reactions, published in 1997-09-01, which mentions a compound: 2689-65-8, mainly applied to heterocyclic compound halo arylation dehalogenation PM3, Category: naphthyridine.
Semiempirical calculations on the transient intermediates involved in the irradiation of haloheterocyclic compounds showed that the difference between the heat of formation of the substrates and that of the radical intermediates derived from cleavage of the C-X bond can be a useful parameter to justify the observed chem. behavior towards arylation or dehalogenation.
Compounds in my other articles are similar to this one(5-Iodo-2-furaldehyde)Category: naphthyridine, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
