Phosphorus Pentachloride (PCl5) Mediated Synthesis of Tetraarylporphyrins

HELVETICA CHIMICA ACTA, Issue 2 2003
Hashem Sharghi
A new synthesis of porphyrins from pyrrole and substituted benzaldehydes is described, with PCl5 as catalyst. Aromatic aldehydes condense irreversibly with pyrrole in the presence of this catalyst, and aerobic oxidation of porphyrinogen provides functionalized porphyrins in yields of 20,65%. [source]

Oligosubstituted Pyrroles Directly from Substituted Methyl Isocyanides and Acetylenes

CHEMISTRY - A EUROPEAN JOURNAL, Issue 1 2009
Alexander
Abstract The formal cycloaddition of ,-metallated methyl isocyanides 1 onto the triple bond of electron-deficient acetylenes 2 represents a direct and convenient approach to oligosubstituted pyrroles 3. The scope and limitations of this reaction (24 examples, 25,97,% yield) are reported along with an optimization of the reaction conditions and a rationalization of the mechanism. In addition, a related newly developed CuI -mediated synthesis of 2,3-disubstituted pyrroles by the reaction of copper acetylides derived from unactivated terminal alkynes with substituted methyl isocyanides is described (11,examples, 5,88,%yield).
