Matrix isolation and theoretical study of the photochemical reactions of C2H3Br and 1,2-C2H2Br2 with CrO2Cl2

Characterisation of photochemically formed reactive species from kinetic and thermodynamic data using UV-Vis. Laser flash photolysis, Time resolved IR and matrix isolation techniques

“…16 The IR spectroscopy indicated the formation of a mixture of bromoacetaldehyde-CrCl 2 O complexes with Z 1 coordination to the aldehyde oxygen or Z 2 coordination to the carbonyl unit. Support for these coordination modes comes from ab initio calculations which indicated that the Z 1 species is the more stable than the Z 2 by some 55 kJ mol À1 .…”
