The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

要約

A new azidonation reaction has been realized on 1,1',4,4'-tetramethyl-2-tetrazene (TMTZ) using iodosylbenzene/trimethylsilyl azide couple (PhIO/TMSN3). This one-step synthesis has led to two azido derivatives: 1-azidomethyl-1',4,4'-trimethyl-2-tetrazene (MATMTZ) and 1,4-di(azidomethyl)-Y,4'-dimethyl-2-tetrazene (DADMTZ). Several conditions were tested such as TMTZ concentration, temperature, and reagent number of equivalents in order to increase the yield of the reaction and to optimize the MATMTZ/DADMTZ ratio. Due to the low thermal stability in solution of these two molecules, we decided to study their decomposition in solution at different temperatures using proton NMR analysis and quantitative NMR. Results showed that DADMTZ is more stable than MATMTZ.
