Preparation method of aromatic phosphine oxide compound

The invention relates to the field of organic synthesis, in particular to a preparation method of an aromatic phosphine oxide compound. The preparation method comprises the following steps: adding a P(O)-H compound, a fluoroaromatic compound and an alkali reagent into an organic solvent, conducting mixing, performing stirring for reaction, and carrying out cooling to obtain a mixed solution; and carrying out washing and extracting to obtain an organic phase, drying and distilling the organic phase, and performing column chromatography to obtain the aromatic phosphine oxide compound. The method is simple in reaction operation, only a proper amount of alkali needs to be added, special reaction conditions such as ligands, catalysts and additives are not needed, the reaction is simple and efficient, and good industrial application prospects are achieved.

NiCl 2as a Cheap and Efficient Precatalyst for the Coupling of Aryl Fluorosulfonate and Phosphite/Phosphine Oxide

Herein, NiCl 2is employed as a cheap precatalyst in the formation of C(sp 2)-P bond via cross-coupling reaction of phenol derivatives and phosphine oxides/phosphites. This catalytic system allows a variety of phenols with diverse functional groups to transform into phosphates with good yields. No additional additive is used in this reaction.

Mn-Catalyzed Electrooxidative Undirected C-H/P-H Cross-Coupling between Aromatics and Diphenyl Phosphine Oxides

C-P bonds are widely found in a great many bioactive compounds and functional molecules. Transition-metal-catalyzed dehydrogenative C-H/P-H cross-coupling plays a crucial part in C-P bond formation since it requires no pretreatment of substrates. Herein, we reported a Mn-catalyzed electrochemical intermolecular dehydrogenative cross-coupling between aryl C-H and diphenyl phosphine oxides. In undivided cells, a series of phosphorylation or diphosphorylation products could be obtained separately by adjusting the proportion of substrates. A catalytic amount of inexpensive Mn(II) salt was used, and no external chemical oxidants were needed in this process. A kinetic isotope effect experiment suggested that the C-H activation was not the rate-determining step.
