N-phenyl-1-(4-phenylphenyl)methanimine → 2-{4-[2-([1,1'-Biphenyl]-4-yl)ethenyl]phenyl}-5,7-dichloro-1-benzofuran

Participants

Reaction Steps

Following the procedure given in Example 1b equimolar quantities of the above named 5,7-dichloro-2-(p-tolyl)benzofuran and 4-phenylbenzalaniline were interacted in the presence of potassium tert.-butoxide to give 5,7-dichloro2-{4-[2-(4-biphenylyl)vinyl]phenyl}benzofuran which, following recrystallization from chlorobenzene, melted at 258°-260° C. The wavelength of maximum excitation of this compound was 375 nm., and the wavelength of maximum emission was 431 nm.
