Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 39093-93-1, name is Thiomorpholine 1,1-dioxide. A new synthetic method of this compound is introduced below. 39093-93-1
4-bromomethylphenylboronic acid pinacol ester (50.00 g, 16.84 mmol), 1,1-dioxide thiomorpholine(27.36 g, 20.24 mmol), potassium carbonate (27.92 g, 20.20 mmol) was added to a reaction flask, 250 mL of N,N-dimethylformamide was added, and the reaction was stirred at 80 C. for 4 hours. After cooling to room temperature, the reaction solution was poured into 1250 mL of ice water, stirred for 30 minutes, and the title product was collected by suction filtration. The white solid was 47.2 g, and the yield was 79.7%.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 39093-93-1, we look forward to future research findings about .
