  The permanent electric dipole moment of PtO, PtS, PtN, and PtC

  摘要：

  The permanent electric dipole moments of the ground, and the low-lying excited electronic states of platinum monocarbide, PtC, platinum monoxide, PtO, and platinum monosulfide, PtS, were measured using a molecular beam optical Stark spectroscopic scheme. The determined values were (in Debye): PtO(X 3Σ−) 2.77(2); PtO(A 1Σ+) 1.15(4); PtS[X(Ω=0)] 1.78(2); PtS[B(Ω=0)] 0.54(6); PtC(X 1Σ+) 0.99(5); and PtC(A 1Π) 2.454(3). These results, along with the previous results for PtN(X 2Π1/2) 1.977(9); PtN(d 4Π1/2) 1.05(9) [J. Chem. Phys. 102, 643 (1995)], are used as a basis for a discussion of the nature of the electronic states.

  The organoplatinum compound of C60, C60Ptn (n = 1–2), was prepared either by the reaction of C60 with Pt(dba)2 or by the thermal disproportionation of C60Ptn (n = ca. 1). The C60Ptn obtained catalyzed the hydrogenation of diphenylacetylene regardless of the platinum content. Cleavage of carbon-platinum bonds of C60Ptn (n = ca. 1) was accomplished by the reactions with phosphines or phosphites, which provided general access to (η2-C60)PtL2 [L = phosphines and phosphites].

  C60 的有机铂化合物 C60Ptn（n = 1-2）是通过 C60 与 Pt（dba）2 反应或 C60Ptn（n = 约 1）的热歧化反应制备的。获得的 C60Ptn 可催化二苯基乙炔的氢化反应，而与铂的含量无关。C60Ptn （n = 约 1）的碳-铂键的裂解是通过与膦或亚磷酸盐的反应完成的，这些反应提供了获得 (η2-C60)PtL2 [L = 磷化物和亚磷酸盐] 的一般途径。
