Thermal and photochemical reactivity of Os(HNO)(CO)Cl2(PPh3)2: Evidence for photochemical HNO generation
摘要:
FTIR studies of the thermal and photochemical reactions of Os(N(O)H)(CO)Cl-2(PPh3)(2) (1) are described. Though 1 is relatively stable, it readily reacts when irradiated to form multiple products, including a metal-carbonyl species and N2O, the decomposition product of HNO. The relative yields of products varied depending on whether or not excess CO was present. A model is presented that includes initial photochemical release of HNO from 1 as a significant but not exclusive photoreaction. (c) 2007 Elsevier Ltd. All rights reserved.
