  Synthetic pathway towards substituted polyphenylene dendrimers

• Image Source:

  Scaffold-optimized dendrimers for the detection of the triacetone triperoxide explosive using quartz crystal microbalances

• Mark:

  Scheme 2 

• Associated context:

  Particular  attention has to be given to the cyclopentadienone starting  materials S2–S6 (Scheme 2) which provide upon cycloaddition  and subsequent extrusion of carbon monoxide branching into  the dendrimer scaffold. The tetraarylcyclopentadienones S2–S6  were prepared starting from the corresponding 1,2-diketones in a Knoevenagel condensation.
