Syntheses of 1,3-Bis(1'-alkylpyridinium)cyclopentadienides and the X-ray Crystal Structures of 1,3-Bis(1'-methyl-2'-pyridinium)indenide Bromide and 1-(1'-Methyl-2'-pyridinium)-3-(1''-methyl-4''-pyridinium)cyclopentadienide Bromide

The reaction of cyclopentadienide with excess 2- or 4-bromo-1-alkylpyridinium salts is described.The products may be thought of as alkylpyridinium-substituted fulvalenes or as 1,3-bis(alkylpyridinium)cyclopentadienides.The reaction probably proceeds via a
