Synthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone

An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

synthesis of 2-phosphonobutane-1, 2, 4-tricarboxylic acid

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...

Tiles are rewrite rules with side e ects, reminiscent of both Plotkin SOS and Meseguer rewriting logic rules. They are well suited for modeling coordination languages, since they can be composed both statically and dynamically via possibly complex synchronization and workow mechanisms. In this paper, we give a tile-based bisimilarity semantics for the asynchronous -calculus of Honda and Tokoro ...
