Photochemically induced reductive elimination of ethane from a binuclear methylplatinum complex

Article abstract of DOI:10.1021/om50004a045

Photolysis (362 ± 7 nm) of [Pt₂Me₃(μ-dppm)₂][PF₆], dppm = Ph₂PCH₂PPh₂, in pyridine leads to fragmentation to [PtMe₂(dppm)] and [PtMe(py)(dppm)]-[PF₆] (Φ = 0.6), but in MeCN (Φ = 0.1), acetone (Φ = 1.2 ± 0.3), or CH₂Cl₂ (Φ = 2.0 ± 0.1) photolysis gives a new reaction involving reductive elimination of ethane, followed by further reactions dependent on the solvent. Reductive elimination is at least partially intramolecular as shown by labeling studies.
