ARYLATION OF AZULENE

In the reaction of azulene with phenylhydrazine and an oxidizing agent (Cu(2+)) a mixture of 1-phenylazulene (28percent) with 2-, 4-, and 6-phenylazulenes (27percent in total) is formed; a series of para-substituted phenylazulenes and α-naphthylazulenes were obtained in a similar way.If p-nitrophenylhydrazine is used, selective arylation of azulene (at position 1) and also of dimethylaniline (at the ortho and para positions) occurs.An excess of the oxidizing agent (Cu(2+)) increases and an excess of the reducing agent (arylhydrazine) reduces the selectivity of arylation.Some of the obtained arylazulenes can be used as dichroic coloring additives for liquid crystals.
