Azo Coupling
This is a bit out of my range of knowledge (hence me asking), but I am looking to prepare a dye precursor for a dye called rosindone (Doing a google
search turns up something like 11 hits, the most relevant of which are links to our site's library). The compound is 4-nitro,phenylazonaphthalene (No
idea if I named that correctly). The structure is an azo coupling of benzene with naphthalene (attached to the 1 position) with a nitro group on the 4
position of the naphthalene. Can this be done by adding 1-nitronaphthalene to diazotized aniline, or will it want to attach itself in the 3 position
or on the other ring? If this is the case, any ideas on how to get it into the correct arrangement?
