He found new methods for the synthesis of pyrylium salts (Balaban-Nenitzescu-Praill synthesis), of carbenes, triptamine, serotonin, two new syntheses for the indole nucleus, and a new method of polymerisation of ethylene.
For pyrylium salts with alkyl substituents such as 2,4,6-trimethylpyrylium salts, the best method uses the Balaban-Nenitzescu-Praill synthesis from tertiary butanol and acetic anhydride in the presence of tetrafluoroboric, perchloric, or trifluoromethanesulfonic acids.
