Oxidative addition of benzylic halides to nickel in the metallic state followed by insertion of carbon monoxide generated fromalkyl oxalyl chlorides proceeded smoothly to give symmetrical 1,3-diarylpropan-2-ones in moderate yields.

This work offers a catalytic approach to convergent ketone assembly based upon formal and tandem C–H insertion of diazoalkanes in the presence of limiting amounts of monomeric formaldehyde, which is easily generated as a gas by thermolysis of the inexpensive and abundant paraformaldehyde (∼30 USD/kg). The method forms di-, tri-, and even tetrasubstituted acetones with high efficiency, and it has streamlined

and selectivity: The online detection of the explosivetriacetonetriperoxide (TATP) is an utmost challenge in security research. The great number of events wherein TATP was involved underlines the significance of solutions to trace that particular explosive material. New optimized functionalized polyphenylene dendrimers (see structure) have been synthesized that can be used as powerful affinity systems
