4- bromophenyl 1 -naphthyl

The method is generally applicable to the preparation of aryl isothiocyanates. Using this procedure, the submitters have prepared the following isothiocyanates, with the yields and times of refluxing indicated phenyl, 44%, 8 hours o-chlorophenyl, 46, 8 -bromophenyl, 73, 8 j>-biphenylyl, 49, 6 /3-naphthyl, 70, 10 9-phenanthryl, 70, 10 1-pyrenyl, 72, 10.
