Abstract
Provided is a process for the conversion of a tertiary phosphine oxide to the corresponding tertiary phosphine, comprising at least reacting said tertiary phosphine oxide with a phosphite compound, in the presence of at least a catalyst. Furthermore, provided is a composition comprising at least a tertiary phosphine oxide and a phosphite compound, and optionally a catalyst.
Claims18
A process for the conversion of a tertiary phosphine oxide to the corresponding tertiary phosphine, comprising at least reacting said tertiary phosphine oxide with a phosphite compound, in the presence of at least a catalyst, wherein the catalyst is selected from the group consisting of fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), iodine monochloride (ICl), iodine monobromide (IBr), heterocyclyl halides, haloalkanes, phosphine dihalides, and any trialkyl, cycloalkyl or aryl analogues thereof, and wherein the catalyst loading is comprised between 0.1 and 1 molar equivalents of the tertiary phosphine oxide.
A composition comprising at least:
- a tertiary phosphine oxide and a phosphite compound, and a catalyst, wherein the catalyst is selected from the group consisting of fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), iodine monochloride (ICl), iodine monobromide (IBr), heterocyclyl halides, haloalkanes, phosphine dihalides, and any trialkyl, cycloalkyl or aryl analogues thereof, and wherein the catalyst loading is comprised between 0.1 and 1 molar equivalents of the tertiary phosphine oxide.
