Methods for Preparing Metal Ion Photocages: Application to the Synthesis of CrownCast was written by Kennedy, Daniel P.;Gwizdala, Celina;Burdette, Shawn C.. And the article was included in Organic Letters in 2009.HPLC of Formula: 66943-05-3 This article mentions the following:
Three different synthetic strategies were utilized in the construction of a representative of a novel class of macrocyclic containing o-nitrobenzhydrol group II cation cages I (X = 1-aza-15-crown-5). The binding properties of I and its photoproduct II to several alk. earth metal cations have been studied. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3HPLC of Formula: 66943-05-3).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.HPLC of Formula: 66943-05-3
