Why aryl aldehydes such as 4-N,N-dimethylbenzaldehyde and 4-aminbenzaldehyde fail to afford porphyrin via Adler method?
I recommend this paper as a great one to follow it to synthesis porphyrin
Synthesis and photophysical evaluation of meso-phenyl-1,4-dihydropyridineand pyridine-porphyrin hybrids
thank you
Plz read my article
