A series of new (4-nitrophenylacetylenyl) (aryl) mercury compounds wer
e prepared by the reaction of aryl mercury acetate or aryl mercury hyd
roxide with 4-nitrophenylacetylene under a base condition, The results
of ultraviolet absorption spectroscopic study showed that the reactio
n is reversible, All the compounds were characterized by means of elem
entary analysis, IR, H-1 NMR, electronic and mass spectroscopies.
