PROCEDURE FOR PREPARING 1,2-DIOXETHANE DERIVATIVES FROM FORMULA: FORMULA WHERE T IS POLYCYCALALKYLLIDENO, SUCH AS ADAMANT-2-ILIDENO, R AND R1 ARE ALKYL, ARYLALKYLL OR CYCLOALKYLL, C1-20, EY IS A CHROMOPHOREO-FLUORENE . IT CONSISTS IN REACTIONING A COMPOUND OF FORMULA: FORMULA WHERE T, R1 E AND THEY ARE AS BEFORE, WITH AN AGENT R-ILANTE, SUCH AS R2SO4, IN THE PRESENCE OF AN ALKALINE METAL ALCOXIDE AND IN THE SINE OF A POLAR APPROXIC SOLVENT. THERE ARE OTHER WAYS TO PREPARE THE DERIVATIVES OF THE FORMULA INDICATED, WHICH ARE DESCRIBED IN THE MEMORY. THE COMPOUNDS OBTAINED ARE USEFUL IN CHEMIOLUMINISCENT IMMUNO ANALYSIS, ANALYSIS OF DNA PROBES AND DIRECT ANALYSIS OF ENZYMES. |
