Thirty-three new tetrakis rare earth chelate salts of the type: Piperidinium+ [(Ar-COCH-CO-R)4]−, have been prepared and characterized. Eighteen of these complexes have been examined for their fluorescence properties in solid state at 77°K. Correlations have been drawn between the fluorescence spectra and the possible site symmetries of the Eu3+ ion in europium tetrakis chelates. The i.r. of eighteen
The reinvestigation of acylation reactions of fluorinated aryl methylketones with ethyl esters at 0°C afforded fluorinated 1, 3-diketones in excellent yields.
