1-bromopentane in not given byproducts: CO; Irradiation (UV/VIS); near-UV irradn. in alkane solvents (Ar) in the presence of 0.5M 1-bromopentane at 200K; not isolated, IR;

in further solvent(s) byproducts: CO; Irradiation (UV/VIS); near-UV irradn. (Ar) in alkane solvents at 295K; ratio of Mn(CO)5Cl to product derived from CO loss depends on excitation wavelength, shorter wavelengths favour formation of η5 complex; not isolated, IR;

in not given Irradiation (UV/VIS); irradn. in alkane soln. (Ar; λ>500nm); further product (6 IR bands) believed to be the radical coupling product from (η5-C5H5)Fe(CO)2 and (η1-C5Cl4)Mn(CO)5;

in not given byproducts: CO, bis(pentachlorocyclopentadienyl); Irradiation (UV/VIS); near-UV irradn. (Ar) in alkane solvents contg. O2 at 295K; not isolated, IR;
