Abstract:
The process to prepare a supported phosphine compound of the structure of Formula 1 A: the process comprising the steps of:a) contacting a phosphine of the formula XPR1R2, wherein X is a halogen, with the solid support, resulting in the P in the phosphine attached indirectly or directly to the solid support via a covalent bond, and b) optionally, replacing one or more of R1 or R2 with any other R1 or R2 respectively, wherein: SS is a polymer solid support; R1 is selected from the group consisting of halogen, hydrocarbyl, substituted hydrocarbyl, heterocyclic and substituted heterocyclic; R2 is selected from the group consisting of halogen, cyclic hydrocarbyl, substituted cyclic hydrocarbyl, heterocyclic and substituted heterocyclic; Z is a divalent or trivalent attaching group covalently attached to at least one phosphorus in the phosphine, selected from the group consisting of hydrocarbylene, substituted hydrocarbylene, â€”Oâ€”, â€”Sâ€”, and â€”NQâ€”, where Q is selected from the group consisting of an optionally-substituted hydrocarbyl and halogen; and L is a divalent linking group covalently attached to Z and to SS, selected from the group consisting of optionally-substituted chains of from 1 to 12 linear, branched, and cyclic carbon atoms.
