Abstract

Conversion of Iv to the diamine and then to the iodonium iodide, followed by the usual pyrolysis, gave dimethoxybiphenylene in 2% yield, as glistening lemon yellow plates melting at 108'and forming a picrate crystallizing from alcohol in black needles melting at 125'. All attempts to convert I1 into dihydroxybiphenylene failed, since it was inert to alkaline reagents, as expected, and was rapidly cleaved by acids to give solutions of a deep ...
