The Chlorination of Di-terf-butyl-2-naphthol+
نویسندگان
چکیده
Chlorination of the di-fm-butylation product of 2-naphthol leads to 3,6-di-rm -butyl-l,l-dichloro-l,2-dihydronaphthalen-2-one (4a) instead of l,6-di-rm -butyl-l,3-dichloro-l,2-dihydronaphthalen-2-one (2) as reported [2], The structural proof was mainly offered by 13C NMR spectroscopy. The influence of annelation and chlorine substitution in 1,2-dihydronaphthalen2-ones on <513c=0 is discussed, which is of importance for the use of <313c=0 for a general discrimina tion between orthoand para-quinolide structures.

متن کاملThe self-assembled Ru(bpy)3(PF6)2 nanoparticle on polystyrene microfibers and its application for ECL sensing.
Ruthenium nanoparticle tris(2,2'-bipyridyl)ruthenium(II) bis(hexafluorophosphate) (Ru(bpy)3(PF6)2, RuNP) was self-assembled on polystyrene (PS) electrospun microfibers. The formation of RuNP is attributed to the sulfonated PS (SPS) microfibers' high adsorptive capability of 94% for Ru(bpy)3(2+), as well as the strong interaction between the Ru(bpy)3(2+) and ionic liquid (1-butyl-3-methylimidazo...
