-
Pyridinium ylids 4 were generated as reaction intermediates from the decarboxylation of pyridinium bctaincs 3, which were preparcd from the reactions of α-amino acid ester hydrochlorides with 2,4,6-triphenylpyrylium tetrafluoroborate. Protonation, addition and substitution reactions of 4 with electrophiles werc studied in this paper.
