Article abstract of DOI:10.1007/BF00473448

We achieved the synthesis of 2-benzopyrilium salts with a 2,6-di-t-butylphenyl substituent in position 3 by acylation of 3,5-di-t-butyl-4-hydroxy-3',4'-dimethoxydesoxybenzoin.We carried out a comparison of the concurrent deprotonation of 1-methylene and h
