Sonogashira Coupling was proposed in 1975 by Nobue Hagihara, Yasuo Tohda and Kenkichi Sonogashira. It is a cross-coupling reaction is one of the most used reaction for coupling of aryl or vinyl halides.
The Finkelstein reaction is a Substitution Nucleophilic Bimolecular reaction involves in the exchange of halogen atom. It is named after the Hans Finkelstein, a German chemist.

others in Orgo 2. But it doesn't end there, this topic is often tested on the MCAT, DAT and similar – with a focus on your ability to understand and deduce mechanism intermediates and reaction products.
In this method, without going through a step of direct deprotonation of the compound 4, the dianionic compound could be produced through a metal-halogen exchange reaction. Accordingly, the synthetic reaction seems to have proceeded without depending on the change in the proton acidity. The improved...
Liquid chromatography can be used to purify compounds from these reaction mixtures if classical techniques are not entirely successful, not desirable, or if a high level of purity is desired. This application note describes the small-scale purification of a synthesized drug...
Moreover, during the reaction, additional amounts of the alkyltrialkoxysilane or alkyltrichlorosilane reactants can be added, with water, to continuously yield product. The period of time for total conversion of the reactants to the AMS product depends on the original concentration of the react...
Positive matrix factorization (PMF) analysis is carried out for the first time on proton transfer reaction time-of-flight mass spectrometer (PTR-ToF-MS) datasets of vehicular emission. Statistical analysis helped to associate the emitted VOCs to specific driving conditions, such as the start of ...
