Electric Literature of 78871-05-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.78871-05-3, Name is Di(naphthalen-2-yl)phosphine oxide, molecular formula is C20H15OP. In a patent, introducing its new discovery.

A newly developed aqueous system with acid and phosphide was introduced in which odorless and stable sodium arylsulfinates can in situ generate arylsulfenyl radicals. These radicals have high reactivity to react with alkynes, alkenes, and H-phosphine oxides for the synthesis of alkyl and alkenyl sulfides and phosphonothioates. The control experiments and quantum calculations are also performed to gain insights into the generation mechanism of arylsulfenyl radicals. Notably, the chemistry is free of thiol odors, organic solvents, and metals.

An efficient selective synthesis of C- and O-phosphoryl-substituted phenols from easily available diaryl H-phosphine oxides with quinone monoketals (QMAs) has been developed. With the assistance of opponent characteristic additives (e.g., H2O and Et3N), diaryl H-phosphine oxides could selectively proceed the allylic- and 1,6-substitution to conjugate with the C-/O- positions of QMAs. The reported protocol is green and practical, and represents an efficient method to functionalize C-/O-phosphoryl-substituted phenols with moderate to good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Di(naphthalen-2-yl)phosphine oxide, you can also check out more blogs about78871-05-3

An efficient catalytic asymmetric hydrophosphination of ortho-quinone methides with H-phosphine oxides is established. A chiral bifunctional squaramide is superior to catalyze this enantioselective carbon-phosphorus bond formation, delivering optically active alpha-arylmethyl phosphine oxides in high yields with high enantioselectivities (up to 94% yield, 99:1 er). Additionally, employing in situ-generated o-QMs for this hydrophosphination step economically provides the corresponding phosphine oxides with comparable yield and enantioselectivity.

An efficient and practical method for synthesis of C2-phosphorylated indoles has been disclosed via a metal-free 1,2-phosphorylation of 3-indolylmethanols with H-phosphine oxides or H-phosphonates. This alternative protocol features a broad substrate scope with respect to both 3-indolylmethanols derived from isatins, acyclic alpha-keto amide, alpha-keto ester, 1,2-diketone and simple ketones and H-phosphine oxides or H-phosphonates, moderate to high yields and mild reaction conditions. Mechanistic studies indicate that this reaction proceeds via an unusual direct 1,2-addition pathway, in which the existence of an electron-withdrawing group adjacent to the hydroxyl group of 3-indolylmethanols plays a decisive role.
