RESUMO

Aldeídos aromáticos sofrem condensação aldólica cruzada com cetonas, na presença de sílica-ácido sulfúrico, na ausência de solventes, tendo como produto o a, b aldólico insaturado correspondente, com excelente rendimento. O reagente pode ser reutilizado diversas vezes sem perda do rendimento da reação.
