Jirō Tsuji
Jiro Tsuji (May 11, 1927 – April 1, 2022) was a Japanese chemist, notable for his discovery of organometallic reactions, including the Tsuji–Trost reaction, the Tsuji–Wilkinson decarbonylation reaction, and the Wacker process, Tsuji–Wacker reaction. Early life and education Tsuji was born in Japan in 1927. After attending Kyoto University, Tsuji began his doctoral research at Columbia University under Gilbert Stork studying natural product synthesis, and making contributions to research on the dissolving metal reduction of enones. Independent career His independent career began at Toyo Rayon (now Toray Industries) studying the stoichiometric, and later catalytic carbonylation of PdII-alkene complexes with carbon monoxide. His preliminary results showed that acyl halides and aldehydes could be decarbonylated by Pd0 at high temperatures (200 °C) yielding alkenes; further investigation revealed that stoichiometric quantities of Wilkinson's catalyst was able to a ...

Asian Scientist
''Asian Scientist'' is an English language science and technology magazine published in Singapore. History and profile ''Asian Scientist'' was launched as a blog in March 2011 by Juliana Chan. The blog's popularity eventually led to a partnership with the publishing house World Scientific Publishing, enabling Chan to turn ''Asian Scientist'' into a magazine and serve as its editor-in-chief. Based in Singapore, ''Asian Scientist'' is maintained by a team of professional science and medical journalists, with active contributors from the science, technology and medical communities. The magazine's launch reflects the growing demographic of scientists, engineers and doctors from Asia, and caters to this community with news stories that are both timely and of interest to them. According to the 2010 U.S. National Science Foundation Key Science and Engineering Indicators report, one-quarter of the world's publications are from Asia and one-third of all scientific researchers worldwide ...

Medals Of Honor (Japan)
are medals awarded by the Emperor of Japan. They are awarded to individuals who have done meritorious deeds and also to those who have achieved excellence in their field of work. The Medals of Honor were established on December 7, 1881, and were first awarded the following year. Several expansions and amendments have been made since then. The medal design for all six types is the same, bearing the stylized characters on a Gilding, gilt central disc surrounded by a silver ring of cherry blossoms on the obverse; only the colors of the ribbon differ. If for some reason an individual were to receive a second medal of the same ribbon colour, then a second medal is not issued, but rather a new bar is added to their current medal. The Medals of Honor are awarded twice each year, on April 29 (the birthday of Hirohito, Emperor Shōwa) and November 3 (the birthday of Emperor Meiji). Types Red ribbon First awarded in 1882. Awarded to individuals who have risked their own lives to save ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methyl Jasmonate
Methyl jasmonate (abbreviated MeJA) is a volatile organic compound used in plant defense and many diverse developmental pathways such as seed germination, root growth, flowering, fruit ripening, and senescence. Methyl jasmonate is derived from jasmonic acid and the reaction is catalyzed by ''S''-adenosyl--methionine:jasmonic acid carboxyl methyltransferase. Description Plants produce jasmonic acid and methyl jasmonate in response to many biotic and abiotic stresses (in particular, herbivory and wounding), which build up in the damaged parts of the plant. The methyl jasmonate can be used to signal the original plant's defense systems or it can be spread by physical contact or through the air to produce a defensive reaction in unharmed plants. The unharmed plants absorb the airborne MeJA through either the stomata or diffusion through the leaf cell cytoplasm. An herbivorous attack on a plant causes it to produce MeJA both for internal defense and for a signaling compound to other p ...

1,2-Bis(diphenylphosphino)ethane
1,2-Bis(diphenylphosphino)ethane (dppe) is an organophosphorus compound with the formula (PhPCH) (Ph = phenyl). It is a common symmetrical bidentate ligand in coordination chemistry. It is a white solid that is soluble in organic solvents. Preparation The preparation of dppe entails the alkylation of NaP(C6H5)2 with 1,2-dichloroethane: : Reactions The reduction of dppe by lithium give the disecondary phosphine: : Hydrolysis gives the bis(secondary phosphine). : : Treatment of dppe with hydrogen peroxide produces the phosphine oxides .Encyclopedia of Reagents for Organic Synthesis 2001 John Wiley & Sons, Ltd Selective mono-oxidation of dppe can be achieved by benzylation followed by hydrolysis: : : Hydrogenation of dppe gives the ligand bis(dicyclohexylphosphino)ethane. Coordination complexes Many coordination complexes of dppe are known, and some are used as homogeneous catalysts. Dppe is almost invariably chelating, although there are examples of monodentate (e.g., W(CO)(d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
