Summary: | PROBLEM TO BE SOLVED: To obtain a new compound capable of providing a polymer useful as a material for an electrophotography, or the like and having excellent hole- transport properties, and having a specific nitrogen-containing seven-membered structure. SOLUTION: This new compound is the compound of formula I [(A) is vinylene or o-arylene; R1 to R3 and Y1 to Y3 are each H or a substitutable group, with the proviso that at least one of the Y1 to Y3 is ethenyl; (n) is 0-4; with the proviso that when (n) is 0, the Y3 is an alkyl, ethenyl or an aryl], e.g. a compound of formula II. The compound of formula I in which Y1 or Y2 is ethenyl and (n) is 0 is obtained by brominating or iodizing a compound of formula III, reacting the obtained product with a compound of formula IV (Ra , Rb and Rc are each H or an alkyl; X1 is a trialkyltin, lithium or the like) in the presence of a palladium or nickel catalyst, and further reacting the product with a compound of the formula Y3 -Cl. A polymer derived from the compound of formula I has a high carrier-transporting ability, and when used as an electrophotography or the like, the polymer contributes to high sensitization or the like. |
