I2-Catalyzed Oxidative Coupling of Ketone Oximes and Dialkyl/Diarylphosphine Oxides

, p. 75 - 80 (2021)
A new protocol for the oxidative coupling of ketone oximes with dialkyl/diarylphosphine oxides to synthesize O -(dialkylphosphinyl)ketone oximes has been developed. Hydrogen peroxide is used as a green oxidizing agent, and molecular iodine is used as a nonmetal catalyst. The reaction has a high atom economy, with water as the only byproduct. O -(Dialkylphosphinyl)ketone oximes with 26 examples have been obtained with high yields. Furthermore, the product may be transformed into other molecules, i.e., by reduction.

Figure presented A novel hydroiodation of alkynes (1) using an iodine/hydrophosphine binary system takes place regioselectively to provide the corresponding Markovnikov-type adducts (2) in good yield. This hydroiodation is advantageous in terms of mild conditions, convenient operation, and tolerance to various functional groups.
New approaches to the synthesis of diphosphine dioxides and hypophosphoric acid esters
Nycz, Jacek E.,Musiol, Robert
, p. 310 - 316 (2007/10/03)
An union >P-O- has been applied as an efficient synthetic precursor of four coordination compounds of the R2P(O)-(O)PR 2 type, namely diphosphine dioxides (R = alkyl, aryl) as well as hypophosphoric acid esters (R = alkoxy, aryloxy), in a one-pot reaction. Furthermore, there were elaborated some mechanistic aspects of the origin of the >P(O)-O-(O)PP-O- and >P(O)X (X= Cl, Br) electrophiles. Attention is focused on the synthesis of the >P(O)-(O)P compounds.
