Abstract
Se prepararon 4-isobutilestireno y otros compuestos olefínicos que corresponden a la formula C(R3)(R4)=C(R2)A mediante la reaccion de un compuesto orgánico que tiene la formula AX con un compuesto vinilo o vinil sustituido que tiene la C(R3)(R4)=C(R2)H en presencia de un catalizador que contiene (a) paladio o sal de paladio y (b) un ligando que corresponde a la formula (I) en esta formula A es arilo, arilo sustituido, heteroarilo, heteroarilo sustituido, benzilo, benzilo sustituido, vinilo, o vinilo sustituido; R2, R3 y R4 se seleccionan independientemente de hidrogeno, alquilo, cicloalquilo, alquilo sustituido de cicloalquilo, arilo, arilo sustituido, alcoxi, alquiltio, heteroarilo, heteroarilo sustituido, alcanilo, aroilo, aroilo sustituido, heteroarilcarbonilo, heteroarilcarbonilo sustituido, trifluorometilo y halo; X es cloro, bromo, iodo diazonio; Ar es fenilo, fenilo sustituido, naftilo o naftilo sustituido; R' y R'' se seleccionan independientemente de hidrogeno, alquilo, arilo o arilo sustituidos; y n es un entero de 3-6. Los compuestos olefínicos mediante la reaccion podrían ser carbonilados a los compuesto carboxílicos correspondientes.
