| titleOfInvention | The synthetic method of one kind (E) -3- subunit substituted benzene phthalein compounds |
| abstract | The invention discloses the synthetic methods of one kind (E) -3- subunit substituted benzene phthalein compounds, this method is using pentamethylcyclopentadiene base dichloride rhodium as catalyst, by the way that the series connection cyclization based on carboxyl neighbour's position C-H key function dough, simply, efficiently one-step synthesis (E) -3- subunit substituted benzene phthalein compounds a series of out occur between aromatic carboxylic acids and acrylic ester compound.The present invention has many advantages, such as that raw material is simple and easy to get, catalyst amount is few, easy to operate, reaction condition is mild. |
