TetrahedronAbstract
A series of new N-(pyridylmethyl)azinium salts have been synthesized from 2, 4, 6-triphenylpyrylium tetrafluoroborate. Generation of azinium N-ylides in the presence of base, has been proved by reactions with electrophiles, such as carbon disulphide, phenyl isothiocyanate and with acetylene dipolarophiles.Ministerio de Educación y Cienci
