Preparation and isolation of amine (organo) chromium (iii) complexes in alcoholic media

σ-Bonded organochromium complexes are prepared by the reaction of the 2- and 3-pyridylmethyl chlorides (picolyl chlorides) with bis(amine)chromium(II) ions, where amine = en, ethylenediamine; dap, 1,3-diaminopropane and trien, triethylenetetramine, in alcoholic media. The air-stable species are isol...
