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

ABSTRAKT

A high-pressure liquid chromatography-mass spectroscopy (HPLC-MS) study of the product composition from the catalytic hydrogenolysis of 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazaisowurtzitane (HBIW) and 4,10-dibenzyl-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazaisowurtzitane (DBTA) was undertaken. The hydrogenolysis of HBIW is observed in all possible directions. Debenzylation of DBTA in formic acid results in forming the mixture of 4,10-diformyl-2,6,8,12- tetraacetyl-2,4,6,8,10,12-hexaazaisowurtzitane (DFTA), 4-formyl-2,6,8,12-tetraacetyl-2,4,6,8,10,12- hexaazaisowurtzitane (FTA), and 2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazaisowurtzitane (TA), the contents of which depend on the CHOOH concentration. In aqueous solutions of formic acid the process is complicated by hydrolysis of the amide groups. Some of the hydrolysis products keep the structure of 2,4,6,8,10,12-hexaazaisowurtzitane. Debenzylation of DBTA in mixtures of formic/acetic, formic/propionic, or formic/iso-butyric acids leads to the same mixed products. The procedure of palladium catalyst reuse in the two-stage reductive debenzylation of HBIW was developed and is presented.
