Abstract
Un método para preparar un compuesto de fórmula general (I): **(Fórmula)** donde cada R2 es independientemente H, un grupo alquilo, un metal alcalino, un metal alcalinotérreo, o un grupo que contiene nitrógeno; R3 y R4 son independientemente H, o un grupo alquilo; y R5 es H, un grupo alquilo o **(Fórmula)** donde dicho método comprende las etapas: (a) eliminación azeotrópica de agua del reaccionante de fórmula general (II) **(Fórmula)** donde R1 es CHR3R4; R2, R3, R4 y R5 se definen como antes; y X es un número entre 0 y 20, (b) pirólisis del reaccionante deshidratado (II) a una temperatura de 170°C a 300°C, y (c) opcionalmente, conversión de cualquier anhídrido formado durante la etapa (b) en el ácido o sal correspondiente que tiene la fórmula general (I).
