[（pi-allyl）（PdCl）-Cl-II]（2）在λ（max）=318 nm处的最长波长吸收归属于烯丙基（-）-> Pd-II配体-金属电荷转移（LMCT）跃迁。在主要的光化学步骤中，LMCT激发导致形成烯丙基自由基和（PdCl）-Cl-I，其在乙腈中经历反硝化成金属钯和钯（II）。Pd-II（CH_3CN）（2）Cl ~-_2在λ（irr）=366 nm处形成，φ =0.008。(C)2002 Elsevier Science B. V.保留所有权利。
The longest-wavelength absorption of [(pi-allyl)(PdCl)-Cl-II](2) at lambda(max)=318 nm is assigned to an allyl(-)--> Pd-II ligand-to-metal charge transfer (LMCT) transition. In the primary photochemical step LMCT excitation leads to the formation of an allyl radical and (PdCl)-Cl-I, which in acetonitrile undergoes a disproportionation to metallic palladium and palladium(II). Pd-II(CH3CN)(2)Cl-2 is formed with phi=0.008 at lambda(irr)=366 nm. (C) 2002 Elsevier Science B.V. All rights reserved.
