4-Biphenylselenocarboxylic acid [6], selenium isologue of 4-biphenylcarboxylic acid, was synthesized by the reaction of hydrogen chloride in ether with sodium 4-biphenylselenocarboxylate [4'] prepared from bis(4-biphenylcarbonyl) diselenide [3] and sodium methoxide. The spectral data of [6], a red solid of mp 39.0~40.0°C, were specified. [6] changed to [3] by heating, and to bis(4-biphenylcarbonyl) selenide [7] and [3] by heating in hexane. [6] reacted with methanol to give methyl 4-biphenylcarboxylate, [7] and [3]. The reaction of [6] with phenylisocyanate to gave phenylcarbamoyl 4-biphenylselenocarboxylate [13] and with aniline gave 4-biphenylcarboxanilide [14]. [13] changed to [14] by heating. 1-Adamantaneselenocarboxylic acid (yellow solid of mp 28.0~29.0°C) was also synthesized by the same manner as the preparation of [5] and its spectral data were specified. © 1987, The Chemical Society of Japan.
