Iridium catalysts rewrite the rules for aromatic acylation

Professor Christopher Douglas research graphic on acylation
Minnesota researchers, led by Professor Christopher Douglas, have rewritten the rules for electrophilic aromatic substitution by developing a new catalyst. An iridium/phosphine mixture activates esters like phenyl salicylate and transfers the acyl group to the most sterically accessible position of an aromatic ring.

Xiao Xiao works on Domino HDDA Reaction

Graduate Student Xiao Xiao works on Domino HDDA reaction.
Xiao Xiao, a senior graduate student working in Professor Thomas Hoye's research group, has reported that properly designed polyyne substrates, merely upon being heated, undergo an efficient, domino sequence of net [4+2] cycloaddition reactions initiated by (rate-limiting) benzyne formation. These proceed through naphthyne, anthracyne, and/or tetracyne intermediates. Rapid, bottom-up synthesis of highly fused, polycyclic aromatic compounds results.

Safety Note

American Chemical Society (ACS) President Peter K. Dorhout begins a recent comment in Chemical & Engineering NewsLeading change through a culture of safety, with a safety note about his personal hobby woodworking. The article lists the many safety culture initiatives ACS is pursuing, including another Joint Safety Team workshop at its National Meeting in Boston. Also at Boston, a presidential symposium, “Moving the Safety Values of the ACS Forward,” will provide updates from the first ACS Safety Summit
