分离并表征了第一个金刚烷基铂配合物，即 (COD)Pt(2-Ad)Cl、(dppe)Pt(2-Ad)Cl、(COD)Pt(2-Ad)Me 和 (dppe)Pt(2-Ad)Me（COD = 1,5 环辛二烯，dppe = 1,2-双（二苯基膦）乙烷，Ad = 金刚烷基）。这些配合物表现出相当大的稳定性，包括在溶液中耐加热至 125°C 数天。因此得出的结论是，以前合成铂金刚烷基的障碍是由于金属交换步骤的复杂性，而不是由于最终产品的内在不稳定性。与直觉相反，从 Zn(II) 到 Pt(II) 成功金属转移的关键是通过使用氯化铂前体和金刚烷基阴离子前体均难溶的溶剂来缓慢反应进程。
The first adamantyl platinum complexes were isolated and characterized, namely (COD)Pt(2-Ad)Cl, (dppe)Pt(2-Ad)Cl, (COD)Pt(2-Ad)Me and, (dppe)Pt(2-Ad)Me (COD = 1,5 cyclooctadiene, dppe = 1,2-bis(diphenylphosphino)ethane, Ad = adamantyl). These complexes show considerable stability, including resistance to heating to 125° C in solution for several days. It is therefore concluded that previously existing road blocks to synthesizing platinum adamantyls were due to complications in the transmetallation step, and not due to intrinsic instability of the final product. Counterintuitively, the key to successful transmetallation from Zn(II) onto Pt(II) is imposing slow reaction progress via use of a solvent in which both the platinum chloride precursor and adamantyl anion precursor are poorly soluble.
