Abstract

Un proceso mejorado para la preparacion de un compuesto dioxo substituido con vinilo, en cuyo proceso se hace reaccionar un aldehído de vinilo con un compuesto que tiene tres o más grupos hidroxilo. En particular, la reaccion se lleva a cabo usando un catalizador ácido, en un solvente orgánico que comprende un solvente alifático que forma un azeotropo binario con agua conforme la reaccion es promovida hasta la terminacion.
