Multinuclear n.m.r. and crystallographic studies on , +, and + are described, the structure of the latter being unambigously established for the first time.
C-CN vs C-H cleavage of benzonitrile using [(dippe)PtH]2

The reaction of [(dippe)PtH]2 with benzonitrile at 140 °C produced two products, the C-H-activated adduct (dippe)Pt(H)(2-C 6H4CN) (2) and the C-CN-activated adduct (dippe)Pt(Ph)(CN) (5), with the kinetically favored C-H activation product forming in a significant majority (～18:1). Further reaction showed a formal β-cyano elimination in 2, forming (dippe)Pt(H)(CN) (3) and benzene. Following the elimination, C-H activation of a second benzonitrile by 3 led to three regioisomers of (dippe)Pt(CN)(C6H4CN) (4).

Irradiation at 254 nm of CH3CN/C6H6 or PhCn solutions of produces 2 equiv. of CO2, and in the presence of PhCl or PhI yields .With CO or PhCCPh the products are or CPh)(dppe)>, but in the latter case extended photolysis yields CPh)(dppe)>.Photolysis in the presence of H2 gives a mixture of the + and + cations.Simple elimination of CO2 does not occur in all cases, as illustrated by the formation of when is photolyzed in the presence of methanol.Photochemical reactions of the related complexes (L2 = dppm, dcpe) are also described.
Photoinduced net [2 + 2 + 2] cycloreversion of platinum(II) glycolate complexes: A new approach to the generation of reduced, coordinatively unsaturated metal species and the activation of carbohydrate carbon-carbon single bonds
Andrews, Mark A.,Gould, George L.
, p. 387 - 389 (2008/10/08)
Photolysis of thermally stable (1,2-bis(diphenylphosphino)ethane)platinum(II) glycolate complexes causes a facile net [2 + 2 + 2] cycloreversion of the 2,5-dioxaplatinacyclopentane moiety to give two organic carbonyl compounds and a reactive (dppe)Pt0 intermediate, as shown by trapping with dppe, ethylene, or hydrogen. Photolysis under hydrogen in the presence of (PPh3)4RuH2 leads to hydrocracking of the glycol carbon-carbon single bond.
