Patent ID: 7238841

Claim:
A process to prepare a supported phosphine compound selected from the group consisting of Formulae 1, 2, 3, 4, 5, 6, and 7 wherein: SS is a solid support; A is a divalent group of 1-12 aliphatic or aromatic carbon atoms, linear or branched, optionally containing one or more heteroatoms or organometallic groups; R 1 , R 2 , and R 3 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, heterocycle, organometallic, Cl, Br, I, SQ 1 , OQ 2 , PQ 3 Q 4 , and NQ 5 Q 6 , where Q 1 , Q 2 , Q 3 , Q 4 , Q 5 , and Q 6 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, hydrocarbylamino, alkoxy, aryloxy, and heterocycle, and R 2 and R 3 together, R 1 and R 3 together, or R 1 and R 2 together can optionally form a ring, the process comprising the steps of: a) contacting (i) a phosphine selected from the group consisting of XPR 1 R 2 , XR 3 P—A—PR1R 2 , HP(═O)R 1 R 2 , HP(═O)R 3 —A—PR 1 R 2 , and HP(═O)R 3 —A—P(═O)R 1 R 2 wherein X is a halogen, with (ii) the solid support, resulting in at least one P in the phosphine attached indirectly or directly to the solid support via one or more covalent bonds, and b) optionally replacing one or more substituent of the group R 1 , R 2 , or R 3 with any other R 1 , R 2 , or R 3 .
