Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this study, N,N-spiro cyclotriphosphazene derivatives (1a–4a) with one stereogenic center were synthesized in two steps. Firstly; mono substituted phosphazene compounds [NPClNHCH (1), NPClOCHN (2), NPClOCH-Me-2,4,6 (3), NPClOCH-Bu -2-Me-4 (4)] were prepared. Secondly, these compounds (1–4) were allowed to react with symmetrical difunctional reagent N,N′-diisopropylpropane-1,3-diamine to obtain cyclotriphosphazenes having one stereogenic center. The reaction of NPClXAr (1–4) with N,N′-diisopropylpropane-1,3-diamine was carried out in dichloromethane. Four new N,N-spiro phosphazene compounds (1a–4a) which have one stereogenic center were obtained from these reactions. The structures of these compounds were characterized by H, C and P NMR spectrometry and elemental analyses.
