A reserach team led by Guangfan Zheng and Qian Zhang at Northeast Normal University reported a visible light-mediated photoredox catalytic radical-polar cross-coupling strategy to achieve bifunctionalization of ipso- and para-positions in substituted aromatics. By utilizing the rapid coupling between sulfur dioxide and the dearomatized radical-type Meisenheimer intermediate, the Smiles rearrangement process was successfully delayed. Following radical ipso-cyclization, the inert C–N bond and the para-C–H bond were activated stepwise. This in-situ and para-bifunctionalization mode is complementary to the Catellani reaction, providing a novel strategy for precise multi-site modification of substituted aromatics. The article was published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

In a new study from Northern Arizona University, a group of researchers discovered that when fabricated gold, copper and iron nanocrystals clump together during a lightning-fast chemical reaction, they form pentagonal constructs that strongly resemble natural snowflakes, a phenomenon that holds incredible implications for the future of nanotechnology.

The proinflammatory activation of immune cells called macrophages can be remotely directed using piezoelectric nanoparticles coupled with ultrasound, Boston College researchers report in Scientific Reports. This potentially allows for the precise, on-demand activation of cells specifically at an infection or tumor site, avoiding the toxicity and side effects associated with the systemic administration of traditional therapeutics.
