Application

Palau′Chlor® is an electrophilic reagent that is useful in the chlorination of aromatic and heteroaromatic substrates, as well as the alpha-chlorination of carbonyl compounds. Palau′Chlor® is an air-stable, free-flowing powder that combines reactivity and practicality, providing an excellent alternative to conventional chlorinating agents such as N-chlorosuccinimide and tert-butyl hypochlorite.

The chlorination of β-halo or β,β-dihaloporphyrins with 2-chloro-1,3-bis(methoxycarbonyl)guanidine (Palau'Chlor) proceeded selectively at the neighboring unsubstituted meso position to afford meso,β-dihalo or meso,β,β-trihaloporphyrins. Such oligohaloporphyrins are useful platforms for constructing more-elaborate porphyrin-based extended π systems. For example, meso-chloro-β,β-diiodoporphyrin participated in an efficient single-step
