<pclass="rvps3"><spanclass="rvts8">A reaction substructure query describes the relevant parts which effectively change during the conversion between reactant and product, plus substituents in their nearest neighborhood relevant for restricting the query towards specific geometric arrangements (e.g. for distinguishing primary, secondary or tertiary alcohols). Please note that in </span><spanclass="rvts17">Phoenix ELN</span><spanclass="rvts8"> there’s no need to explicitly assign reaction centers for this.</span></p>
<pclass="rvps3"><spanclass="rvts8">After performing the query, the </span><spanclass="rvts17">Results</span><spanclass="rvts8"> panel combines all matching experiments into distinct groups sharing the same reaction, sorted by yield. These groups in turn are sorted by their maximum yield item. This provides a result list with the most relevant items first.</span></p>
<pclass="rvps3"><spanclass="rvts8">In substructure queries, explicit substituents are essential for restricting the results to what you want. As a rule, no specified substituent means that any substituent is allowed for a match. In our example, without the explicit hydrogen bonds specified, also e.g. the conversion of a ketone to an ether also would be part of the results. The illustration below explains the role of explicit substituents in more detail (of course, explicit substituents generally are not restricted to hydrogen):</span></p>

<pclass="rvps7"><spanclass="rvts42">The</span><spanclass="rvts41"> Synthetic Connections</span><spanclass="rvts8"> overview identifies and visually maps the entire network of synthetic pathways leading to, and originating from the reaction of the experiment currently displayed in the ELN.

<pclass="rvps30"><spanclass="rvts8">This overview is accessible from the button located at the bottom right corner of the current reaction sketch:</span></p>
