Abstract

Un proceso para preparar ciclopropilacetileno, que comprende los pasos de: (a) mezclar al menos 1,0 equivalentes de una base fuerte en un solventeaprótico con un equivalente de 5-halo-1-pentino en un solvente aprótico a una temperatura desde alrededor de -20 hasta alrededor de 150°C; (b) permitir quela temperatura de la mezcla de reacción se eleve a un rango desde alrededor de 0 hasta alrededor de 150°C y mantener la temperatura dentro de este rango poral menos 15 minutos, o hasta que la ciclización se complete substancialmente; (c) opcionalmente enfriar la mezcla de reacción a una temperatura desdealrededor de -30 hasta alrededor de 50°C; (d) enfriar o apagar la rección con cualquier fuente de protones; y (e) opcionalmente, purificar el producto final.
