Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 131274-22-1, Name is Tri-tert-butylphosphonium tetrafluoroborate, Recommanded Product: Tri-tert-butylphosphonium tetrafluoroborate.
5-Carbapterocarpens, one of them displaying estrogenic activity, were prepared from alpha-aryltetralones in high yields through a one-pot, BBr3-promoted O-demethylation and cyclization sequence. The key alpha-aryltetralone intermediates were obtained by direct alpha-arylation of tetralones with o-alkoxybromoarenes in the presence of Pd2(dba)3 (2.5 mol-%) and tBu3PHBF4 (10 mol-%) as catalysts, together with 2.5 equiv. of KOH in dioxane/H2O (4:1), under microwave irradiation conditions (80 W, 100 C, 40 min), leading to alpha-monoaryltetralones in good yields.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: Tri-tert-butylphosphonium tetrafluoroborate. In my other articles, you can also check out more blogs about 131274-22-1
