Abstract
A compound of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and represent an alkyl group or combine with the nitrogen atom to form a ring, and X represents a pyridyl group, a quinolyl group, or a pyridyl or quinolyl group substituted by at least one alkyl or alkoxy group; a process for preparing the compound and an electrophotographic material containing the same.
Claims24
An electrophotographic material comprising a support having thereon at least one layer comprising a binder and a compound of the formula:
- ##STR22## wherein R.sub.1 and R.sub.2 are the same or different and are an alkyl group or combine with the nitrogen atom to form a 5- or 6-membered ring, and X is a pyridyl group, a quinolyl group, or a pyridyl or quinolyl group substituted by at least one alkyl or alkoxy group.
A compound of the formula:
- ##STR23## wherein R.sub.1 and R.sub.2 are the same or different and are an alkyl group or combine with the nitrogen atom to form a 5- or 6-membered ring, and X is a pyridyl group, a quinolyl group, or a pyridyl or quinolyl group substituted by at least one alkyl or alkoxy group.
A process for producing a pyrazoline compound of the formula:
- ##STR24## wherein R.sub.1 and R.sub.2 are the same or different and are an alkyl group or combine with the nitrogen atom to form a ring, and X is a pyridyl group, a quinolyl group, or pyridyl or quinolyl group substituted by at least one alkyl or alkoxy group, which comprises reacting a tin complex salt of a hydrazino compound of the formula:
- X.NH.NH.sub.2 wherein X is as defined above, with a distyryl ketone of the formula:
- ##STR25## wherein R.sub.1 and R.sub.2 are as defined above, in dimethyl sulfoxide.
