Co-ordination Kinetics of Some Aliphatic Amines towards the Photogenerated Transient 'CoH3'

Article abstract of DOI:10.1039/DT9880002675

Time-resolved adsorption spectra were observed after nitrogen-laser flash photolysis of toluene solutions of in the presence of some aliphatic amines, and second-order rate constants were evaluated for co-ordination of the amines to the co-ordinatively unsaturated transient 'CoHL3' photogenerated.The steric bulk of substituents on the amine nitrogens is a dominant factor in the magnitude of the constants.The CoHL3(amine) adducts were also formed upon continuoes photolysis with a high-pressure mercury lamp, and found to be stable at temperatures lower than -40 deg C, on the basis of their (31)P n.m.r. and visible absorption spectra.
