Three-Coordinated Aminotroponiminate and Aminotroponate Complexes of Gold(I)

Potassium N-isopropyl-2-(isopropylamino)troponiminate, K{(iPr)2ATI}, and potassium N-cyclohexyl-2-(cyclohexylamino)troponiminate, K{(Cy)2ATI}, were synthesized by treatment of the neutral ligands with an excess of KH in
THF. Reaction of the potassium reagents with [AuClPPh3] resulted in the gold complexes [Au{(iPr)2ATI}PPh3] and
[Au{(Cy)2ATI}PPh3]. The solid-state structures of both compounds, in which the ligands are arranged in plane,
show distorted trigonal planar coordinated gold atoms. Potassium 2-(isopropylamino)troponate (K(iPrAT)) and the
cyclohexyl analogue (K(CyAT)) were obtained by deprotonation of corresponding aminotropones with KH. In an
analogous fashion the gold complexes of composition [Au(iPrAT)PPh3] and [Au(CyAT)PPh3] were prepared by
reaction of K(iPrAT) and K(CyAT) with [AuClPPh3], respectively.

将中性配体与过量氢化钾（KH）在四氢呋喃（THF）中反应，成功合成N-异丙基-2-(异丙氨基)卓酮亚胺酸钾（K{(iPr)2ATI}）与N-环己基-2-(环己氨基)卓酮亚胺酸钾（K{(Cy)2ATI}）。将上述两种钾试剂与[AuClPPh3]（三苯基膦氯化金）反应，分别得到金配合物[Au{(iPr)2ATI}PPh3]与[Au{(Cy)2ATI}PPh3]。两种金配合物的固态结构均呈现如下特征：配体采取平面排布方式，中心金原子为畸变平面三角形配位构型。通过将相应的氨基卓酮与氢化钾（KH）去质子化，得到2-(异丙氨基)卓酮酸钾（K(iPrAT)）及其环己基同系物K(CyAT)。以相似的合成策略，使K(iPrAT)与K(CyAT)分别与[AuClPPh3]反应，即可得到组成为[Au(iPrAT)PPh3]与[Au(CyAT)PPh3]的金配合物。
