which consists of two benzene molecules joined together by two nitrogen atoms linked by a double chemical bond.
The double bond prevents the benzene group at each end from rotating around the axle linking them.
#'Parachuting'boron on benzene rings (Nanowerk News) Tuning the para position of benzene moieties is significant for creating biologically active compounds and optoelectronic materials.
Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring.
Chemists at ITBM, Nagoya University have developed a novel iridium catalyst that enables highly para-selective borylation on benzene,
Itami and his coworkers have generated a new catalyst that uses steric interactions with the benzene substituent,
making it possible to conduct late stage diversification of core structures containing benzene. The study, published online on April 10, 2015 in the Journal of the American Chemical Society("para-CH Borylation of Benzene derivatives by a Bulky Iridium Catalyst),
The positions right next to the substituent on the benzene i e. the ortho-(2-or 6-)positions are blocked usually by the substituent during C-H borylation.
However, a mixture of meta-(3-or 5-)products and para-(4-)products are observed usually in a 2: 1 ratio upon C-H borylation of a monosubstituted benzene.
and materials science for creating benzene-containing functional molecules, I figured that para-selective C-H functionalization would be an extremely useful technique for the late-stage diversification of core structures.
Caramiphen, an anticholinergic agent used for the treatment of Parkinson's disease contains a monosubstituted benzene moiety along with ester and amine groups.
You have this polymer that s made from carcinogenic compounds like benzene and it will last up to 10,000 years.
