A mild robust generic protocol for the Suzuki reaction using an air stable catalyst was written by Moseley, Jonathan D.;Murray, Paul M.;Turp, Edward R.;Tyler, Simon N. G.;Burn, Ross T.. And the article was included in Tetrahedron in 2012.Product Details of 827-01-0 This article mentions the following:
A mild but robust procedure was developed as a 1st pass generic protocol for the Suzuki-Miyaura reaction. The protocol employs an air stable Pd pre-catalyst at low loading (闂? mol%) in aqueous solvent mixtures at moderate temperature using K2CO3 as base. Under these mild conditions, most aryl bromides will react with sterically and electronically demanding arylboronates to give complete conversion to the product biphenyls in <1 h. Aryl chlorides are also fully converted in most cases either under identical conditions in 8-24 h, or in 2 h at elevated temperature A further advantage of these mild conditions of moderate temperature, weak base, and benign solvent is that sensitive functional groups and structural motifs are well tolerated. In addition, the lipophilic biphenyl products are readily isolated after a simple work-up procedure. These generic conditions are ideal for proof of transformation, and as the starting point for development and optimization of a specific process. In the experiment, the researchers used many compounds, for example, 5-Chloroindole-3-carboxaldehyde (cas: 827-01-0Product Details of 827-01-0).
5-Chloroindole-3-carboxaldehyde (cas: 827-01-0) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Product Details of 827-01-0
