In the Full Paper by H. Gao and co-authors, incorrect values for the melting point, decomposition temperature and 13 CN MR chemical shifts of triazolium 2,4,5-trinitroimidazolate (6)w ere given.The correct values are given below.The above errors were caused by the analysis of an impure compound.A sar esult, the meltingp oint, decomposition temperature and 13 CN MR spectrumf or the salt 1,2,4-triazolium 2,4,5-trinitroimidazolate ( 6)a re unfortunately incorrect.The correct values are:m eltingp oint 216.5 8 8C( 58 8Cmin À1 )a nd 217.2 8 8C( 10 8 8Cmin À1 ); the decompositiont emperature 232.5 8 8C( 5 8 8Cmin À1 )a nd 250.8 8 8C( 10 8 8Cmin À1 ); and the 13 C NMR spectrum shifts at 146.8, 143.7,1 38.3 ppm ([D 6 ]DMSO solvent).These valuesr eplace the originald ata: T m = 146.48 8C; T d = 220.5 8 8C; and 13 CN MR shifts:1 47.7, 144.6, 139.2, 136.2 ppm.The discussion and conclusions are not changed.The authorsa pologize for the errors and for any inconveniencec aused.
In 1974 a DuPont patent2 disclosed the synthesis of cyclen phosphine oxide, 2,3 by hydrolysis of cyclen fluorophosphorane, 1. In this paper we wish to report the synthesis of a series of compounds (structure 4) that are higher homologues of 2. Oxides 4 have been synthesized by hydrolysis of the corresponding ionic chloride salts, 3, which we previously reported.4 (Curved lines in structures 3 and 4 represent ethylene or trimethylene bridges.) Oxides 4 in each case are volatile compounds that have an intense molecular ion in their mass spectra. 31P NMR studies have been useful in characterizing these compounds as phosphine oxides. Physical and NMR properties of structures 4 are collected in the Table. Table: Physical and Spectroscopic Data for 4. Two of the oxides, 5 and 6, shown in the Table can exist in only one structural form. Both 5 and 6 show only one phosphorus NMR signal at +25.8 and +11.7 ppm, respectively, similar to
