Abstract

Fluorinations of non-perfluorinated elementorganics by free fluorine are still little familiar to preparative chemists. Besides the problematic handling of gaseous fluorine this may be due to the prejudice of a low selectivity. By the F 2-addition to low-and medium-valent organic derivatives of the p-elements {(R-) nE} I want to show systematically that the interaction of elemental fluorine does not lead necessarily to the cleavage of the element-carbon bond or to the destruction of the organic periphery by non-specific CH-substitution. ▪ E ≙ element of 4. – 7.th main group - e.g.: C, P, As, Sb, Bi, S, Se, Te, I R ≙ organyl The importance and range of this ‘oxidative liquid-phase fluorination’ shall be demonstrated by the alternative preparations of element - fluorides and the synthesis of hitherto unknown classes of compounds.
