Process for the preparation of 3,5-disubstituted isoxazoles
A novel process for the preparation of 3-bromo- and 3-chloro-5-substituted isoxazoles is provided. Dibromo- or dichloro-formaldoxime is reacted with an excess of an 1-alkyne derivative of the formula where R is hydrogen, phenyl or 1-6 C alkyl optionally substituted by halogen, OH, OR’, CHO, COR’, COOR’, CONH2, CONR’R” or NHCOR’ where, in turn, R’ and R”, which may be the same or different, are a 1-6 C alkyl or haloalkyl, in the presence of (i) at least an equimolecular amount, with respect to the dibromo- or dichloro-formaldoxime, of an alkaline base selected from the class consisting of sodium and potassium carbonate and bicarbonate and (ii) an inert solvent in which the 1-alkyne is soluble at room temperature.
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 6567-35-7
