Ishida, Naoki published the artcileStereoselective synthesis of trisubstituted alkenylboranes by palladium-catalysed reaction of alkynyltriarylborates with aryl halides, Name: Triphenyl(pyridin-1-ium-1-yl)borate, the publication is Chemical Communications (Cambridge, United Kingdom) (2007), 4381-4383, database is CAplus and MEDLINE.
The palladium-catalyzed reaction of alkynyltriarylborates with aryl halides afforded trisubstituted alkenylboranes, in which two different aryl groups were installed across the carbon-carbon double bond in a cis arrangement.
Chemical Communications (Cambridge, United Kingdom) published new progress about 971-66-4. 971-66-4 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene, name is Triphenyl(pyridin-1-ium-1-yl)borate, and the molecular formula is C23H20BN, Name: Triphenyl(pyridin-1-ium-1-yl)borate.
