254-60-4, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 254-60-4, Name is 1,8-Diazanaphthalene,introducing its new discovery.
The reaction of (pentamethylcyclopentadienyl)lithium with lead(II) chloride leads to Me5C5PbCl (1) or (Me5C5)2Pb (2) depending on the stoichiometry.The half-sandwich complexes Me5C5Pb(BF4) (3a) and Me5C5Pb(CF3SO3) (3b) are formed from 2 by reaction with tetrafluoroboric acid and trifluoroacetic acid, respectively. 2,2′-Bipyridine and 1,8-naphthyridine react with 3a and 3b to yield the 1:1 adducts 4a, 4b, and 5.An X-ray structure analysis of 3a shows the presence of BF4-bridged dimeric units.Based on 1H-, 13C-, 11B-, 19F-, and 207Pb-NMR data, the bonding in the ?-complexes is discussed. – Key Words: Decamethylplumbocene protonation / Half-sandwich lead compounds / Lead(II) ?-complexes: 207Pb NMR / (Pentamethylcyclopentadienyl)lead tetrafluoroborate, crystal structure
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 254-60-4, and how the biochemistry of the body works.254-60-4
