Two new unsymmetrical (R)PNP(R')-type pincer ligands based on a bis(tolyl)amine framework have been synthesized and characterized by a variety of techniques, including X-ray crystallography. These ligands have been coordinated to Ni, Pd, and Pt precursors to provide a number of well-characterized group 10 halides. Conversion of these metal halides to metal hydrides was accomplished using borohydride reagents, or by direct interaction of the ligand with the zerovalent metal precursor. The insertion of oxygen into these hydrides in an attempt to prepare metal hydroperoxides has been examined; however, we were unable to obtain stable and isolable hydroperoxide species.
两种新的不对称 (R)PNP(R')-型夹式配体基于双(甲苯基)胺骨架已经被合成并通过多种技术进行了表征，包括 X 射线晶体学。这些配体已经与 Ni、Pd 和 Pt 前体配位，提供了一系列得到很好表征的第 10 族卤化物。通过使用硼氢化物试剂或通过配体与零价金属前体的直接相互作用，将这些金属卤化物转化为金属氢化物。我们还研究了将氧插入这些氢化物中以制备金属过氧化物的方法；然而，我们无法获得稳定和可分离的过氧化物物种。
