Abstract

Results General. The photochemical experiments were performed with filtered light (cut-off 435 nm, 5 cm water IR-filter, from a 300 W incandescent lamp) as described before, 7 and small samples were withdrawn for analysis at suitable intervals. The work-up procedure, involving evaporation of solvent and excess tetranitromethane, was conducted at a temperature< 0 C. The crude product mixtures were stored at—78 C and were analysed (' ...
