文摘

Various R/Ar-functionalized tin 5,10,15-tris(pentafluorophenyl)corrolate derivatives are reported herein including the first ferrocenyltin corrolate species. The isopropyl, sec-butyl-, 2-methyl-n-butyl-, phenyl-, 2-thienyl-, and ferrocenyltin species have been prepared and characterized through ¹H, ¹³C, and ¹¹⁹Sn HMQC NMR spectroscopy, mass spectrometry, UV鈥搗is and photoluminescent spectroscopy, and cyclic voltammetry studies. J_C/H鈥揝n NMR spectroscopic couplings and ring-current effects (upfield shifting) were determined for the R鈥揝n axial hydrogen and carbon atoms. This report adds to older conceptually similar reports, by, i.e., Janson et al. (J. Am. Chem. Soc. 1969, 91, 5210) and Walker et al. (J. Am. Chem. Soc.1983, 105, 6923鈥?929), as discussed herein. Such NMR spectroscopic aspects are discussed for these model systems. Compound Sn鈥揚h bond cleavage was achieved by treatment with I₂.
