Impossible reactions: 5 chemistry rules broken – New Scientist
http://www.newscientist.com/special/impossible-chemistry
quasixtal, oscill. BZ rxn, XePtF6, 3-atom carbocat., QM tunnels
…and a longer version:
(1) quasicrystals & Shechtman Nobel;
(2) BZ reaction as wave via autocatalytic intermediate synthesis, damped so not to violated 2nd law; (3) Bartlett’s XePtF6 via super oxidizer (i.e. electron grabber) PtF6;
(4) Olah’s carbocation spread over 3 atoms (causes reaction to join on a different C than predicted)
(5) odd tunneling effects with intermediates push reactions to seemingly unfavorable products
