Behavior of formylphenol derivative complexes of uranyl ion in alcoholic media

Journal Article · · J. Coord. Chem.; (United States)

The reaction of 2,6-diformyl-4-methylphenol, H(MDA), with boiling ethanol yields the acetalated species 2-diethylacetal-4-methyl-6-formylphenol, H(EAC). Consequently the dioxouranium(VI) complexes (UO/sub 2/(EAC)/sub 2/) and ((C/sub 2/H/sub 5/O)/sub 2/CH-OC/sub 6/H/sub 2/CH/sub 3/-HC=N(CH/sub 2/))/sub 2/XUO/sub 2/ /X = NH, (UO/sub 2/(NEAC)); X = S, (UO/sub 2/(SEAC)/ have been isolated. When condensation is carried out in boiling methanol, the complex ((CH/sub 3/O)/sub 2/CH-OC/sub 6/H/sub 2/CH/sub 3/-HC=N(CH/sub 2/)/sub 2/)/sub 2/NHUO/sub 2/, (UO/sub 2/(NMAC)), is obtained. The compounds bearing the NH group in the chain under substitution of one of the acetal groups with the formyl group, yielding the species (Y/sub 2/CH-OC/sub 6/H/sub 2/CH/sub 3/-HC=N(CH/sub 2/)/sub 2/-NH-N(CH/sub 2/)/sub 2/-NH-N(CH/sub 2/)/sub 2/=CH-CH/sub 3/C/sub 6/H/sub 2/O-CHO) UO/sub 2/(Y=OEt and OMe). Ligands and complexes have been characterized by infrared, /sup 1/H and /sup 13/C NMR spectroscopy and by thermogravimetric measurements.
