Our recent work on AC electrolysis for organic synthesis is just published by @J_A_C_S! Our first JACS paper on organic synthesis!! 2 years of hard work and 200+ pages SI! Congrats to my students and postdoc! Thanks to @NIGMS for the support! Check it out! https://t.co/tN8AIlrN7G
pubs.acs.org
Here, we report a unique electrosynthetic method that enables the selective one-electron oxidation of tertiary amines to generate α-amino radical intermediates over two-electron oxidation to iminium...
We are very excited to share our latest work on #electroorganic synthesis using AC electrolysis! Check out our lastest @chemrxiv, where we control one- or two-electron oxidation of amines for selective amine functionalization by AC frequency! @NIGMS

As a chemical reaction travels along these actuators, disulfide crosslinks break, releasing mechanical strain, which allows chemical signals to pass between separated objects @LabSemenov @ArpitaPaikar @WeizmannScience Read the article: https://t.co/an9JI8xqHp
