Abstract
Inhaltsübersicht. Mittels 205Tl‐Breitlinien‐ und hochauflösender 1H‐NMR wurden Tl(I)‐sowie Organothallium(III)‐Verbindungen untersueht und 205Tl‐ und 1H‐chemische Verschiebungen sowie 205Tl‐1H‐Kopplungskonstanten ermittelt. Die NMR‐Parameter dor Tl(I)‐Verbindungen wurden mit Literaturwerten verglichen. Die paramagnetischen 205Tl‐Verschiebungen von Verbindungen des Type R2TlX (R = Me, Et. n‐Pr, Ph; X = NO3, F, Br, J) werden in Bezug auf Substituenten., Losungsmittel‐ und Konzentrationseinflüsse diskutiert. Auf der Basis eines 0.3 molaren wäßrigen TINO3‐Primärstandards werden die 205Tl‐Verschiebungen in einer einheitlichen Verschiebungsskala geordnet und nach bindungstheoretischen Gesichtspunkten verglichen.205Tl‐N.M.R.‐Spectroscopical Studies on Thallium(I) and Organothallium(III) Compounds Tl(I) and organothallium(III) compounds are investigated by means of 205Tl wide line and high resolution 1H‐n.m.r. and 1H chemical shifts as well as 205Tl‐2H coupling constants are estimated. The n.m.r.‐parameters of the Tl(I) compounds are compared with the values of the literature. The paramagnetic 205Tl shifts of compounds of the type R2TlX (R = Me. Et, n‐Pr. Ph; X = NO3, F, Br. I) are discussed with reference to the influence of substituents, solvents, and concentrations. The 205Tl shifts are arranged on the basis of a 0.3 M aqueous TlNO3 primary standard in a uniform shift scale and compared as to theoretical aspects of chemical bonds.Für die großzügige Unterstützung unserer Arbeit danken wir Herrn Prof. Dr. K.‐D.
