Arylselenenyl fluorides ArSeF are obtained from diselenides Ar2Se2 or arylselenotrimethylsilanes ArSe-SiMe3, and XeF2. They are detected by low-temperature 19F and 77Se NMRspectroscopy. Substitution in the ortho position of the aromatic ring to provide electronic or steric protection is a requirement for their formation. ArSe--F compounds decompose according to 3 ArSe-F-->[ArSe-SeF2Ar]+ArSe-F-->ArSeF3+Ar2Se2

Triphenylphosphane(2,4,6-tri-t-butylphenylseleno)gold(I) and bis-(2,4,6-tri-t-butylphenylseleno)mercury(II) are obtained from chloro(triphenylphosphane)gold(I) or mercury dichloride with lithium(2,4,6-tri-t-butylphenyl)selenide and with trimethyl(2,4,6-tri-t-butylphenylseleno)silane, respectively. Molecular mass determinations and 1H, 13C and 77Se NMR spectra indicate that both new compounds are monomeric
三苯基膦(2,4,6-三叔丁基苯基硒基)金(I)和双-(2,4,6-三叔丁基苯基硒基)汞(II)是从氯(三苯基膦)金(I)或二氯化汞与(2,4,6-三叔丁基苯基)硒化锂和三甲基(2,4,6-三叔丁基苯基硒基)硅烷。分子量测定和1 H,13 C和77 Se NMR光谱表明,这两种新化合物在溶液中均为单体。
