摘要：

[Pt2Me2(CO)2(μ-η1-C5H4PPh2)2] (2), obtained by reaction of [Pt2Me2(μ-η5-C5H4PPh2)2] (1) with CO, has been characterized by X-ray crystallography as a face-to-face dimer, in which the cyclopentadienyl ring is 1,2-substituted. Thermolysis of 2 at 55 °C yields acetone and the platinum(I) dimer [Pt2(CO)2(μ-C5H4PPh2)2] (3), and the crystal structure of the latter reveals that the platinum atoms have migrated to the ipso carbons of the cyclopentadienyl rings. The analogous [Pt2{P(CH2CH2CN)3}2(μ-C5H4PPh2)2] is produced, along with ethane, when 1 is treated with P(CH2CH2CN)3. © 1990, American Chemical Society. All rights reserved.
