Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 791616-63-2, Name is (11bR)-4-Hydroxy-2,6-bis(2,4,6-triisopropylphenyl)dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, Computed Properties of C50H57O4P.
An Investigation of the Wittig Reaction between a Series of Monosubstituted Phthalic Anhydrides and Ethoxycarbonylmethylidenetriphenylphosphorane
The title reaction has been investigated using a range of phthalic anhydrides substituted at the 3- or 4-positions with electronically dissimilar functional groups.The structures of the 3-ethoxycarbonylmethylidenephthalides formed in these reactions have been determined by both chemical and spectroscopic means.The regioselectivity of attack by the phosphorane on an unsymmetrical phthalic anhydride appears to be largely dependent upon the electronic effects of the substituent which render one of the anhydride carbonyls relatively more or less susceptible to nucleophilic attack.In general, (E)-ylidenephthalides are formed predominantly.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Computed Properties of C50H57O4P. In my other articles, you can also check out more blogs about 791616-63-2
