Abstract
A process to prepare substituted aryl pnictogen derivatives comprising contacting a fluoropolyether or fluoroalkyl primary bromide or iodide, with a pnictogen derivative such as triaryl phosphine, triaryl arsine, or triaryl stibine or triaryl phosphine oxide, triaryl arsine oxide or triaryl stibine oxide, to produce the corresponding fluoropolyether- or fluoroalkyl-substituted aryl phosphine oxide, aryl arsine oxide or aryl stibine oxide; and optionally, contacting the oxide product with a reducing agent to form the corresponding substituted aryl phosphine, arsine or stibine.
Claims21
A process to prepare a fluoropolyether- or fluoroalkyl-substituted aryl stibine comprising contacting a compound selected from the group consisting of fluoropolyether primary bromide, fluoropolyether primary iodide, fluoroalkyl primary bromide and fluoroalkyl primary iodide, with a triaryl stibine or triaryl stibine oxide to produce the corresponding mono-substituted, di-substituted, tri-substituted, or a combination of two or more thereof, fluoropolyether- or fluoroalkyl-substituted aryl stibine oxide, wherein the process is performed in the presence of one or more of a radical initiator, a solvent and a catalyst.
