Rapidly fluctuating AC targets specific carbonyl groups in the presence of several reducible groups

US chemists have developed an electrochemical approach that precisely reduces single specific carbonyl bonds in molecules containing several. Rather than applying direct current (DC) as is usual in electrochemistry, Phil Baran’s team at Scripps Research Institute in La Jolla, US, use rapidly alternating polarity (rAP). With this they selectively reduce just one carbonyl in various complex imide compounds.
