| abstract | NEW FREE RADICALS HAVING THE FORMULA: 1-(O-),2-R1,3-(R2-OOC-),4-(R3-OOC-),5-R4-PYRROLE IN WHICH R1, R2, R3 AND R4 ARE C1-C4 ALKYL RADICALS (METHYL, ETHYL, N-PROPYL, ISO-PROPYL, N-BUTYL, ISO-BUTYL, AND TERTHUTY) MAY BE PREPARED FROM AN ALKYL ALKANOYLACETATE. THE ALKANOYLACETATE IS DIMERIZED OR REACTED WITH ANOTHER ALKYL ALKOYLACETATE TO GIVE DIALKYL (X,B-DIALKANOYL) SUCCINATE WHICH, AFTER CYCLISATION WITH HYDROXYLAMINE GIVES 1-HYDROXY-2,5-DIALKYL-3,4-DI (ALKOXYCARBONYL) PYRROLE WHICH IS OXIDISED TO 1-OXYL-2,5-DIALKYL-3,4-DI (ALKOXYCARBONYL) PYRROLE AMONG THE RADICALS OF THE ABOVE GROUP, 1-OXYL-2,5-DITERBUTYL-3,4-DIETHOXYCARBONYL PYRROLE IS PARTICULARLY SUITABLE FOR USE IN NUCLEAR MAGNETIC REASONANCE MAGNETOMETRY. |
