IIT Madras
The Indian Institute of Technology Madras (IIT Madras or IIT-M) is a public technical university located in Chennai, Tamil Nadu, India. It is one of the eight public Institutes of Eminence of India. As an Indian Institute of Technology (IIT), IIT Madras is also recognized as an Institute of National Importance. Founded in 1959 with technical, academic and financial assistance from the then government of West Germany, IITM was the third Indian Institute of Technology established by the Government of India. IIT Madras has consistently ranked as the best engineering institute in India by the Ministry of Education's National Institutional Ranking Framework (NIRF) since the ranking's inception in 2016. History In 1956, the West German Government rendered technical assistance to establish a state-of-the-art engineering institute in India. Soon, the first Indo-German agreement was signed in Bonn, West Germany in 1959 for the establishment of the Indian Institute of Technology i ...

George Olah
George Andrew Olah (born Oláh András György; May 22, 1927 – March 8, 2017) was a Hungarian-American chemist. His research involved the generation and reactivity of carbocations via superacids. For this research, Olah was awarded a Nobel Prize in Chemistry in 1994 "for his contribution to carbocation chemistry." He was also awarded the Priestley Medal, the highest honor granted by the American Chemical Society and F.A. Cotton Medal for Excellence in Chemical Research of the American Chemical Society in 1996. After the Hungarian Revolution of 1956, he immigrated to the United Kingdom, which he left for Canada in 1964, finally resettling in the United States in 1965. According to György Marx, he was one of The Martians. Early life and education Olah was born in Budapest, Hungary, on May 22, 1927, into a Jewish couple, Magda (Krasznai) and Gyula Oláh, a lawyer. After the high school of Budapesti Piarist Gimnazium, he studied under organic chemist Géza Zemplén at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbocations
Carbocation is a general term for ions with a positively charged carbon atom. In the present-day definition given by the IUPAC, a carbocation is any even-electron cation with significant partial positive charge on a carbon atom. They are further classified in two main categories according to the coordination number of the charged carbon: three in the carbenium ions and five in the carbonium ions. Among the simplest carbocations are the methenium (a carbenium ion), methanium (a carbonium ion), acylium ions , and vinyl cations. Until the early 1970s, carbocations were called ''carbonium ions''. This nomenclature was proposed by G. A. Olah. Carbonium ions, as originally defined by Olah, are characterized by a three-center two-electron delocalized bonding scheme and are essentially synonymous with so-called ' non-classical carbocations', which are carbocations that contain bridging C–C or C–H σ-bonds. However, others have more narrowly defined the term 'carbonium ion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol Economy
The methanol economy is a suggested future economy in which methanol and dimethyl ether replace fossil fuels as a means of energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products. It offers an alternative to the proposed hydrogen economy or ethanol economy, although these concepts are not exclusive. Methanol can be produced from a variety of sources including fossil fuels (natural gas, coal, oil shale, tar sands, etc.) as well as agricultural products and Municipal solid waste, municipal waste, wood and varied biomass. It can also be made from chemical recycling of carbon dioxide. Nobel prize laureate George A. Olah advocated a methanol economy. Uses Fuel Methanol is a fuel for heat engines and fuel cells. Due to its high octane rating it can be used directly as a fuel in flexible-fuel vehicle, flex-fuel cars (including Hybrid electric vehicle, hybrid and plug-in hybrid vehicles) using existing internal combustion engi ...

Trifluoromethyltrimethylsilane
Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF3) is an organosilicon compound with the formula CF3Si(CH3)3. It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group. The compound was first prepared in 1984 by Ingo Ruppert and further developed as a reagent by G. K. Surya Prakash. Preparation The reagent is prepared from trimethylsilyl chloride and bromotrifluoromethane in the presence of a phosphorus(III) reagent that serves as a halogen acceptor. Use in organic synthesis In the presence of a metal salt (M+ X−), the reagent reacts with aldehydes and ketones to give a trimethylsilyl ether, the net product of insertion of the carbonyl into the Si-CF3 bond. Hydrolysis gives trifluoromethyl methanols. The reagent also converts esters to trifluoromethyl ketones. A typical initiator is a soluble fluoride-containing species such as tetrabutylammonium fluoride; however, simple alkoxides ...
