Charge-transfer absorption of olefins with nitrosonium. structural relevance to the dimethylbutene complex with dinitrogen tetraoxide
The transient electron donor-acceptor (EDA) complexes of various olefins (dimethylbutene, etc.) with the nitrosonium acceptor (NO+) show diagnostic charge-transfer absorption bands in dichloromethane solutions at low temperatures. Since the same charge-transfer absorption bands are observed when olefins are exposed to dinitrogen tetraoxide, they are ascribed to analogous EDA complexes [olefin, NO+] NO3- that are derived from the ionic disproportionation of nitrogen dioxide.
