Quecksilberorganische Verbindungen. 32. Synthese von Fluorophenylquecksilber-Verbindungen durch DecarboxylierungDie Organoquecksilber-Verbindungen HgR2 (R = s. Abstract) und RHg(O2CR) (R = s. Abstract) wurden in mäßig-guten bzw. niedrigen Ausbeuten durch Decarboxylierung der entsprechenden Quecksilber(II)-fluorobenzoate in siedendem Pyridin erhalten. Im Gegensatz dazu ergab Quecksilber(II)-2,3,4,5-tetrafluorobenzoat eine gering Menge von CO2, Spuren an Hg(o-HC6F4)2 und sehr wenig an o-HC6F4Hg(O2CC6F4H-o). Die 199Hg-NMR-Spektren der Diorganoquecksilber-Verbindungen (R = s. Abstract) werden diskutiert.
Notes:
The organomercury compounds HgR2 (R = 2-Cl,6-FC6H3, 2,6-F2C6H3, 2,3,6-F3C6H2, m-HC6F4, p-HC6F4, or C6F5) and RHg(O2CR) (R = 2-Cl,6-C6H3, 2,6-F2C6H3 or 2,3,6-F3C6H2) have been obtained in moderate - good and low yields respectively from decarboxylation reactions of the corresponding mercury(II) fluorobenzoates in boiling pyridine. By contrast, mercury(II) 2,3,4-5-tetrafluorobenzoate gave a low yield of CO2, a trace of Hg(o-HC6F4)2 and a very low yield of o-HC6F4Hg(O2CC6F4H-o). The 199Hg NMR spectra of the diorganomercurials (R = 2-Cl,6-FC6H3, 2,6-F2C6H3, 2,3,6-F3C6H2, 2,4,6-F3C6H2, 2,6-Cl2C6H3, o-HC6F4, m-HC6F4, p-HC6F4 or C6F5) are discussed.
