Gold-phosphido-monolayer-protected clusters (MPCs) of 1-2-nm diameter, Au(x)(PR2)y, analogues of the well-known thiolate materials Au(x)(SR)y, were prepared by NaBH4 reduction of a mixture of HAuCl4.3H2O and a secondary phosphine PHR2 in tetrahydrofuran/water. In comparison to the Au-thiolate MPCs, fewer of the larger phosphido groups are required to cover the surface, and the Au-P bond is not cleaved as readily in reactions with small molecules as is its Au-S counterpart. 31P NMR spectroscopy provides a direct method to study cluster formation and the interaction of the phosphido ligand with the gold surface.
通过在四氢呋喃/水中用硼氢化钠还原氯金酸三水合物（HAuCl₄·3H₂O）和仲膦（PHR₂）的混合物，制备了直径为1 - 2纳米的金磷化物单层保护簇（MPC），即Au(x)(PR₂)y，它是著名的硫醇盐材料Au(x)(SR)y的类似物。与金硫醇盐MPC相比，覆盖表面所需的较大磷化物基团较少，并且在与小分子反应时，金 - 磷键不像其金 - 硫对应键那样容易断裂。³¹P核磁共振光谱提供了一种直接的方法来研究簇的形成以及磷化物配体与金表面的相互作用。
