Bisquinolinol and bisbenzoquinolinol compounds, and process for producing same

摘要

A bisquinolinol or bisbenzoquinolinol compound is disclosed which has the formula CH2=C(CH-R1)2 wherein R1 represents a 8-hydroxy-7-quinolyl group which may have an alkyl group at the 2-position thereof or a 10-hydroxy-9-benzoquinolyl group which may have an alkyl group at the 2-position thereof. The bisquinolinol and bisbenzoquinolinol compounds may be obtained by thermal rearrangement of a bisquinoline or bisbenzoquinoline compound of the formula CH2=C(CH2-O-R2)2 wherein R2 represents a 8-quinolyl group which may have an alkyl group at the 2-position thereof or a 10-benzoquinolyl group which may have an alkyl group at the 2-position thereof. The bisquinolinol and bisbenzoquinolinol compounds are useful as an extractant for metal ions.
