The present invention provides a polarizing film having a high dichroic ratio. The polarizing film includes a disazo compound represented by the following general formula (1). In the general formula (1), Q represents a substituted or unsubstituted phenyl group or a substituted or unsubstituted phenyl group having a heterocyclic ring; non-adjacent carbon atoms of the phenyl group may be substituted with nitrogen atoms; R
1
represents an alkyl group; R
2
represents a hydrogen, an acetyl group, or a substituted or unsubstituted benzoyl group; n represents 1 or 2; and M represents a counter ion.

A (3+2) cycloaddition reaction of linear N,N-disilyl enamines and organic azides is investigated. The N,N-disilyl enamines, derived from the selective double hydrosilylation of conjugated nitriles, are employed in-situ for this investigation. The resulting triazoline intermediate from the (3+2) cycloaddition reaction promptly undergoes retro-(3+2) cycloaddition to yield versatile non-stabilized diazoalkane
