Abstract

<p>Two-coordinate group-15 element centered radicals that bear a lone pair and an unpaired electron on the same group-15 atoms have received much attention in group-15 element chemistry. We previously synthesized an isolable dialkylphosphinyl radical, 2,2,5,5-tetrakis(trimethylsilyl)-1-phosphacyclopentane-1-yl (<b>1P</b>) and its antimony and bismuth analogues (stibinyl radical <b>1Sb</b> and bismuthinyl radical <b>1Bi</b>) as persistent radicals. We report herein (1) synthesis of an isolable cyclic dialkylarsinyl radical <b>1As</b> that exists in the radical form both in solution and in the solid state and (2) comprehensive study of a series of neutral two-coordinate pnictogen-centered radicals (<b>1P</b>, <b>1As</b>, <b>1Sb</b>, <b>1Bi</b>) including UV-vis spectra, redox properties, and reactions.</p>
