Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Computed Properties of C7H4ClN, 623-03-0, Name is 4-Chlorobenzonitrile, molecular formula is C7H4ClN, belongs to nitriles-buliding-blocks compound. In a document, author is Liu, Zhuqing, introduce the new discover.
Selective 1,4-Addition of Organolithiums to Maleate Monoesters with Application for a Short Efficient Route to Azaindanones
The ability of maleate half-ester salts to serve as electrophilic partners in 1,4-conjugate addition reactions with control of regioselectivity has previously been explored in only a limited context with soft nucleophiles. We have demonstrated that benzylic anions of picolines, as well as enolates of ketones, esters, and nitriles, react with lithium 4-( tert -butoxy)-4-oxobutenoate in a completely regioselective manner. This new method was applied to an expedient two-step process for preparing a key azaindanone intermediate for the clinical-candidate drug MK-8666.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 623-03-0. Computed Properties of C7H4ClN.
